[@TheNico8008]

Doing math with a sharpie? That's bold bro lol. But really huge thanks, this saved me from a diabolical math test

[@jaydezuniga55]

who is here because of online classes? (just curious)

[@_aragornyesyes_7171]

me

[@aki9071]

for our performance task actually

[@ameirrivas1018]

Me😭

[@jessir.3832]

me....

[@amitvirk7243]

im failing math rn

[@merediththomas526]

i literally cried about math all day today because i didn’t know what to do after i get the length and width set up for the quadratic. this made me have the “OHHHH” moment i was so desperately craving. THANK YOU!

[@patrickjmt]

@GunsNBananas yes, every single one. it is a prerequisite

[@Xamoona]

you're brilliant!! my math teacher talks to himself when he teaches!:S

[@joshmanu9154]

Donya Rezaei same 😂

[@sammysamgurl]

more helpful then a math tutor website i wasted $50 on!!

[@vaitavellienangie6969]

Thanks so much teacher,you are an angel 😂🎉

[@ArmanAbdulZahoor]

No need to get so aggressive. If a person is misinformed or makes a mistake, people shouldn't just insult them. It would help to tell them what is right and wrong

[@BreeZeTSHQ]

best online teacher for sure

[@rainxdsan9563]

Good thing there are still this kinds of vids if not I failed my exam already

[@gelo2993]

ok gonna say my thanks to this vid,, it helped me alot.. It saved me from what I thought was a error

[@Yoobster]

I got a math culminating and this dude explains these math units better than my teacher lmao

[@wasd6287]

how do u get the link again?

[@Kramswodahs]

How'd you do the square root thing? Good video though. I didn't get anything from my teacher and you just made me get it a whole lot more. Thanks.

[@Lallushe]

It's a quadratic formula. To find the 2 solutions for the question you need to apply the formula.

[@sulaearts]

Wonderful! Having to go back and knock some of the dust and spiderwebs out of my brain after being out of school for 15 years. Your video was a great "swiffer" for my dusty old brain!

[@nino22nb]

Thanks, this video really helped me

[@zhen7800]

Thank you so much this video helped me get 95 in my math i had a hard time undertanding what my teacher taught

[@Yoobster]

During covid they had teachers working crazy fast and sloppy

[@gabriellerose02]

This helped so much!!!! Thank you

[@katesboon1047]

how to do checking???

[@foodmenuart923]

Very well explained! 👌🏻👍🏻🌿

[@LiveGoodPhilippines888]

thank you so much for this sir

[@FilmedbyNeil]

Y so true my math teacher was right handed then she broke her wrist and had to do plastic surgery on her right wrist, now she uses her left hand

[@deecandelariavaldez5948]

Uhh can someone tell me where did the 4 came from?

[@richardriguard1394]

That's just part of the quadratic equation, dont know why its three, just is

[@terrylarkin2562]

When you complete the square of ax^2+bx+c you get the quadratic equation

[@gmh2374]

Dee Candelaria Valdez it’s from the quadratic formula which says -b+/-square root of b^2-4ac all divided by 2

[@joshmanu9154]

Ghemar you forgot the a after 2

[@omgwtfbbqlmaorofl]

cant u just complete the square or factor it

[@SebastianRocks1234]

completing the square finds the vertex and factoring it won't do much it'll just simplify it.

[@0jizzy090]

I just don't get one thing, you use 114.4 to represent the area but in the question it says 114.4^2 is the area. Why is that?

[@choppchopp9975]

my maths teacher barley even taught this stuff in class and just gives us a oile of homework on this. i have no idea how to do any of them and here i am watching videos from 2010...

[@bossguy8301]

Thanks

[@mileshontiveros6134]

The three sides of a right triangle form three consecutive even numbers. Find the lengths of the three sides how do i solve this

[@mayonnaiseman6950]

saved my ass, thank you so much bro exactly what i was looking for

[@avneilshivika878]

yessss brooooo thankkss man

[@mariahvillanueva921]

Can someone help me with this? An Airplane flies 900 miles against a headwind of 25 miles per hour.The plane took 15 minutes longer for this flight than with a tailwind of 25 miles per hour.How fast can the plane fly in still air?

[@axerotic2038]

Mariah Villanueva about 6 miles

[@zion639]

you are a godsent

[@jeremiahdavis2786]

Thank you so much that helped a lot I’m taking notes

[@xxsurajbxx]

Thank you for existing

[@DrachenIvy]

oh thank god i got a math test tomorrow

[@smalth]

can you put fast plane rate as r+50 and time as t-2

[@shebinbabu3832]

wow he estimated 25.566 and it was right i know hes good

[@Capreeca]

well taught.

[@xwywy122x]

you amazingtastic sir, i am left handed too! :D

[@valeriee8211]

How do you know it was W= instead of L= ??

[@michaelpiotto4988]

valeriee I doesn’t matter witch is what as long a one variable has w plus 14

[@soniaashipala6008]

why did he made the length as length plus width.please help

[@gmh2374]

Length is width+14 Because it was given in the question

[@bluehairsugagotjams4487]

May i ask, is this through extracting square roots?

[@hnng1439]

omg an army. pls support us buddies (gfriend's fandom) no, its not through extracting square roots.

[@ThePloopStudio]

Our teacher doesn't let us use quadratic formula unless she tells us to lmfao.

[@Tom-rf5gk]

where had this video been for the past few months?

[@kylejohnson8516]

be respectful

[@jirahaustin3866]

can you solve this problem? . a rectangular lot has an area of 240m . What is the width of the lot if it requires 64 m of fencing materials to enclose it? thank you in advance!... btw. i`ve try to do it but there is some things that im not sure if correct.

[@grayson-bubbles-light5025]

+jirah austin you didn't quite specify the width being smaller or larger than the length, so I'll do the width when it's lager and smaller. All you do is find a factor of 240 where both numbers can add up to 32. You do 32 because you're working with perimeter with the fencing, so you must either multiply the width and length by two and add together of add them together first then multiply by 2. So, 12 and 20 are your answer. The width is either 12 or 20 (again, it was not specified)

[@jirahaustin3866]

Tnx random dude ... I hope that ...you can help me again.

[@clashofclansdogdowlers4111]

why is it -4 (1) not positive 4 in the quadratic equation

[@gmh2374]

ClashOfClans Dog Dowlers because the formula says b^2-4ac

[@Mostwanted225]

Thank u alot

[@Lallushe]

Very nice :)

[@gdogvibes1]

perfect

[@hanako_ovo_milkshake572]

Suggestion uhm can u show solution and not ur hand

[@alluremaureen935]

Keyyah Velo lol because he is left handed 😂

[@michaelpiotto4988]

Left handed life struggles lol

[@JoshPity]

@0jizzy090 That's square meters, not squaring the number itself :P

[@rovelrahman8083]

WTH -4*-144.4 =577.6

[@chizzwigwe7740]

great video thanks

[@abdulhadifovad]

i like the way you pronounce length :p

[@alienmancat2504]

Quadratics unit test after tomorrow GGs

[@mustanserhussain2595]

Can u help me do this question ,the answer is 4 :) a rectangle has length (x+9) and width x what is the value of x this is a gcse question chapter 7

[@victarine]

if its a quadratic equation it should probably be x.x + 9x - 4 = 0 i suppose... i may be completely wrong since im in maths intermediate and also 8 years late hahahah

[@LaSikSee]

can u tutor me???

[@itsmesofia8312]

wow thanks

[@birukindrias3294]

Would you solve this word problem A person on tour has dollar 360 for his daily expense. If he extends his tour for 4 days, he has to cut down his daily expense by dollar 3. Find the new original duration of the tour.

Oh sorry ignore my last comment. I understand it now

[@jnushrat]

niceee :D

[@stickshiftstarship]

Huh, that's really not as hard as my book made it sound.

[@GunsNBananas]

are all math teachers left handed?

[@jesuisravi]

nice j0b

[@pattheranga6279]

yeah... no
