Just wanted to let you know that you are the best math person on KZbin. You don't mess around, you are extremely simple, and not confusing. Thank you. You are the reason I'm going to pass my final tomorrow

[@patrickjmt]

@DJOEllis glad the video helped! i have tons of algebra stuff so dig around if u get stuck elsewhere

[@patrickjmt]

@Sennnsie what are you trying to do? find the roots? it is already factored in this case, so just set the stuff inside the parenthesis equal to zero and solve.

[@TheJjc93]

You really are the most simple and effective math tutor on youtube. I appreciate you writing it out in bold marker instead of drawing it on a computer which is harder to understand at times. thanks ill be passing tests now

[@ionocean]

Patrick - Thank you, and all you others who have videos out there explaining the quadratic formula/solution. I am 51 yrs old now, had oodles (very sci. term there) of math in high school, and even more later; now using these vids for a refresher!!!!! Just what I needed, Thx!!!!! Mike

[@TheCurlygirl89]

I rarely ever comment on videos but I started off from being very very confused with my homework to completely understanding it like a pro in a matter of 5 minutes. Thank you so so much!

[@patrickjmt]

@grendlldog glad that i could help

[@patrickjmt]

i try to make the types of math videos i would like to watch :) straight and to the point!

[@patrickjmt]

yep! no problem!!

[@patrickjmt]

@mbdsfan1 you could make one side zero and try to factor (it will not factor though). the question really is: what number squared, then multiplied by 2 is going to equal a negative number though?

[@patrickjmt]

my pleasure!

[@patrickjmt]

@MrTobi1226 glad i could help : )

[@matthewoneill8353]

I think I have watched all of your videos. You do a great job of explaining how to do this stuff. Thanks!

[@patrickjmt]

@solarprophet23 ha, yes, you read my mind. :) but it happens. people are often frustrated by the time they show up here and end up venting a little, so i understand ;) everyone acts a bit crazy on the internet from time to time i think

[@patrickjmt]

early video,was still working out image/audio quality at that point

[@GaiaBlader]

Patrick, I really appreciate all the help you've given me through these videos!

[@inoxicrom]

dude, this is much easier for me to learn, i can use my earphones and just listen and not get distrupted. cheers

[@mo0sey]

I've got a math final tomorrow and this is really going to help, thank you very much! Also, you have really great handwriting.

[@dan_g.]

I have finals tomorrow, and I honestly can't thank you enough. You're the best math tutor on here for sure. :D

[@weareoneofficial]

Hey man i just wanted to say you have done an awesome job to guide me in my add maths. Great thanks to you so i can understand better. You are one of a kind who doesn't needs HD videos to get subscribers. Another Subscriber coming in. (Y)

[@patrickjmt]

if you are trying to put the entire problem into your calculator all at once, you might try breaking it down into small parts, and do more computations. calculator syntax must be exact, or you obviously get the wrong answer! this is why i stopped using calculators and became better at math as a result

[@aingaran2003]

Thanks man your videos are really helping me out with pre calc! Your way better then the teachers we have at school =)

[@patrickjmt]

@TrumpetMan2013 why does that matter?

[@RALMAR9]

That fuzzy sound in the backround is a bit annoying but its bearable since you're a great teacher. thankyou Patrick

[@imahyper1]

thanks for jogging my memory! doing summer work (ew) and realized ID LOST EVERYTHING I LEARNED IN ALGEBRA 2! you've been really useful!!!!!

[@hidbulbzrus]

IDK how someone could complain. This kind of thing is priceless for a college student.

[@musikmachine4]

Your videos are saving my life, thank you!

[@crazypanchito]

Thank you that second example help me out a lot.

[@LovingmySavior]

gee whiz people, he could do this in about 1/2 a second in his head if he wanted, but he's trying to go slow and explain to us how to do this a different way... don't complain when someone's trying to help you!!! thanks Patrick, you are a great teacher :)

[@patrickjmt]

@misscarol1203 welcome to the internet

[@ForeverAlone79]

7 people don't get it. Very excellent job on your video series. These are amazingly helpful. Thanks!

[@patrickjmt]

it is not a race : ) there are situations where completing the square is very much needed (such as when you start integrating rational functions in calculus)

[@issacxc]

Thank you so much. You helped me get through the whole sophomore year and you're still helping me get through Junior year. Thank you, thank you

[@MKelements]

I hope you continue making these videos!

[@patrickjmt]

@aimangoescoolify over 5 minutes to slowly explain how to do this process to someone who does not know how to do it, is more accurate.

[@patrickjmt]

@hiebs3 quadratic formula

[@liamjames4294]

This video helped so much! Thanks a lot :)

[@vortex000131]

Just the revision I needed.

[@patrickjmt]

you do it so that things become a perfect square... you should also think about why it works instead of throwing up your hands and saying: you did not tell me why it works.

[@patrickjmt]

i am still working on mine too...

[@patrickjmt]

@edamcheeseisyummy it is ' they're', not 'there', mr einstein.

[@GargoyleEmperor]

Alright, in the 2nd problem (@ 8:56) after you've factored out your 2. You mentioned you didn't want to factor the 2 out of the 10. Whereas my natural instinct was to toss the 10 on the other side of the equal sign and divide by 2 to keep fewer numbers on my paper. What was the reason you didn't want to do this, if you don't mind my asking? not questioning your method, just looking to learn for later problems. Thanks and great video!!

[@Plantsandtoyhorses]

i think I have seen the other video you are referring to. In that one you took -6x and multiplied it by half, getting a -3, that you squared to get positive 9. But in that one you added the 9 in ()s, but also subtracted 9 from the constant 8 to get -1 And left the 0 alone. in this one you add 25/4 to the 0 because you added inside the ()s. Why didn't you add 9 to the 0 in the other video? Or what makes this equation different?

[@nickludwig5]

you're a real life saver thank you

[@bobsmith952]

Thanks man for the video, great help!!

[@kolimo81096]

thanks i frogt how to do competing the and i had completing the squre on my final exam review study your video helped remer real quick thanks

[@mika8226]

thanx so much man u really helped me!!! :D

[@stuffinaboxguy]

best part about this: me:"Huh? i zoned out!" *rewinds video*

[@kaylenbarringerpokefandj]

this confused me because that's not how my teacher taught me

[@firdauseahmad4551]

thank you (: for your tutorial. finally I can understand completing the square (:

[@Zaya2499]

It took me 5 videos and I finally fully am up to date with my algebra class

[@andrewbcassel]

Thank you Patrick.

[@jonjon4796]

the vid was very helpful, actually the same problems in my assignment

[@WHY70122]

@remi: bring the 1 on the left side of the equation to the right side, dont forget to change sign. That will make the eq has the form of ax^2 + bx +c =0 and you got it from there.

[@ZamoraMediaUSA]

you're a life saver! God bless you (:

[@4TrollinFun]

HELP....at 4:30 where did you get that 4 that u multiplied 6/1 from?

[@funkperson69]

YOU ARE A GENIUS !!!!!!!!!!!!!!!!!!!!!

[@PullaPatonki]

Thanks so much for this :)

[@kurousagi7349]

thanks a lot it really help me in my college algebra :) \m/

[@Frankyboy1177]

That's too complicated for me^^But you seem to be very good at math, good job dude ;)

[@cinnamonmolly]

Yayyy!!! Thanks, Patrick! :)

[@nba2kganers]

thanks man! you rock!

[@fabiolapena8398]

I really like the way you explain things. The way your brain processes info is similar to mine :) Lefties rule! Math is so hard for me though :( I think after a good cry of frustration it clears the fog in it. I am so happy I found a lefty mathematician!

[@nick90267]

Another great video.....

[@mick5000x]

@blendistars much more easier to say that because decimals are usually more complicated inalgebra.

[@patrickjmt]

you dont sound so angry to me, angryguy :)

[@AwUs2020]

Man you are my teacher.. hahahaha.. i lkie your video.. thats helping me for mid year exam..

[@maisei425]

UR AMAZINGGG THNX ALOT

[@shivanishah6626]

in ur first video of completing sure, you did not move the square part in the right side. u just put it into left side but in this video you move it right. is there any difference? please clear my confusion sir

[@CrazyBlonde2393]

ur a life saver!!!!!!!!

[@cras17]

@GargoyleEmperor That is perfectly fine. I would have done it like that as well. Both methods will get you the answer.

[@figsrule011]

thnx soo much but could you subtract the 6 before you take half of b and square it (25/4)?

[@xTaraSheltonx]

Do you have any videos that explain how to solve quadractic equations like this where it DOESN'T equal to zero? thank you!

[@JOSHMAN2012]

thank you so much

[@Prime-o8f]

Hang on, when you got to root 1 divided root 4, don't you get root 1 divided by 2 - not 1/2. Please explain, I'm confused. Great video by the way, extremely helpful.

[@ragtimest]

thank you sir

[@patrickjmt]

@eudnes so do not watch. what is so difficult about that for you to understand? instead, you just keep trolling the same video. go make your own, or at the very least, just go away.

[@christopherstum6884]

If you wish to understand why, I recommend that you watch a sequence of three videos (in order) that I have dedicated to explaining the process known as completing the square. You can find the said videos by browsing my account.

[@toastmalone5778]

Thank you. So. Much.

[@sugarcoated122]

you're amazing!

[@patrickjmt]

i guess you did not listen to what i said... of course it is easy. i did it in like .10 seconds in my head... that is not the point

[@AlchemistOfNirnroot]

Brackets are like a family; parentheses is just one part of it.

[@ToniJason2011]

thank you

[@DanteJ]

How come this time what was created by 5/2 ^2 (25/4) didn't get subtracted from 6, it got added to 0?

[@GogoTq1]

what if the question says complete the square but there's not =0 ? ... is there difference ? i really need help asap !!

[@mick5000x]

finally i understand ty ty ty ty "D

[@beAbubblyblonde]

can you please solve y^2 - 40y + n in completing the square?

[@shotboi657]

thank you for this vid

[@AimeeFallon1]

How would you do 2x^2-11x-16=0 and get it into vertex form? Please help!!!

[@28switangel]

how to use this method to find the minimum point of curve? I'm confused! Pls help me out!

[@BardocksSynphony]

@MrTobi1226 its because you have the power to pause.. rewind. you are also not faced with pressure from peers and teacher while in class so your learning process becomes easier. thank god for the internet am i right?

[@comicreaper]

yeah im really having trouble with this but im starting to understand.

[@remy161]

Whats the answer if its like just two!? For example. X(square)+2x=1?????

[@mediina1]

very nice

[@TrumpetMan2013]

What if the coefficient of the X^2 term is odd?

[@ilovefoodandmusic1]

the only reason I'm passing maths is because of these videos hahahahhaha

[@osixmini9159]

Nice. ...tnx

[@daywattly]

huh, (x= -2) (x= -3), -2 + -3= -5 the five in the x^2+5x+6=0 is positive.where did you get the negitive? I understand that -2 times -3 = the 6 but -2 plus -3 does not =5 but -5

[@johnhoang6356]

Isn't the answer from completing the square give you the same answer from just using ac factoring?

[@frankpezzulo8284]

what if the number that you find the square root of (in this case 9) isn't a perfect square, like maybe 11?
