you're out here saving lives,thank you kind sir.

[@lizziepadalecki8116]

THANK YOU SO MUCH. Math has been absolutely destroying me even though I have never worked so hard in school in my whole life. Thank you.

[@costanzaa-fl]

[@tdjkhazard4522]

Dude thank you. Whenever I ask for help my math teacher always says “you should’ve paid attention” or “I already taught this”

[@winterrain1947]

I had teachers like that. Impossible to learn from someone who thinks you should totally understand everything the first time it was explained.

i am 22 years old. Preparing to enroll into online college classes your videos have provided with so much information then before. I genuinely feel more confident and brave enough to solve any mathematical which comes my way. You are doing a terrific job teaching these stuff. Very huge round of applause

[@renewd]

You are an excellent teacher and I thank you for this presentation. I'm happy you didn't end at about 45 minutes when you said you were done, that's when things got really interesting. Your clarification of when to use the absolute value sign on the variable was so clear and concise. This was exactly what I was looking for and I am very grateful to you.

10:40 a square root can have 2 answers on that case -2.5 or 2.5

[@crumfit1232]

No, that's only when you take the square root on both sides of the equation, that equation already had the square root so its not plus and minus. Same reasoning the square root of 25 is just 5, not 5 and -5.

[@jin_cotl]

11:50 I think you still have to foil this even if it’s positive

[@samanthadisanti2729]

Do you only check to see if the solutions work if there are two solutions or should you do it every time? For example: Would I check with just the solution x=9? Or would I check if it was a quadratic and there were two zeroes found?

[@iamathing7510]

I know I am not the person that made this video, however if it helps, I believe I have an answer! My teacher told me that you must always check the answers you get (whether it is two solutions or not). I am not sure if my teacher was wrong, but either way checking your answers is a good idea! ^^ I hope this helped!!

[@lilisosa8713]

Thank you for this video , it really help me !!!!

[@roaahedaya1779]

should I always plug in the solutions in the equation to make sure that the soultions satisfy the equation?

It's not a bad idea. I usually check whenever I have at least two solutions.

Math makes my head hurt 🤯

[@didequen3339]

for the equation of sqrt(x+1) = 2x-13. Before you do anything else, you must condition it x+1 >= 0 and 2x-13 >=0 therefore solution must be greater than 13/2 = 7.5. once you get solution, you can immediately drop x=5.25 out, keep x=8

[@kingkovic7830]

can you explain a bit more on how you did the condition x+1>=0 and 2x-13=0 so that i can understand everything else. thx

[@raylittlerock3940]

3:45 In Blitzer I see this rule : If X^(n/m)=A then, IF n IS EVEN, then, X= PLUS OR MINUS A^(m/n) In the equation that is solved here, n=2, so n is even. So (1) (x-4)^2/3=4 (2) (cube root of x-4) ^2 =4 (3) cube root of x-4 = plus or minus (square root of 4)=plus or minus 2 (4) (cube root of x-4)^3 = ( plus or minus 2)^3 = plus or minus 8 (5) x-4=plus or minus 8 (6) x = 12 or x= -4 Is this correct?

If there is no number next to the equal sign do we say it is equal to zero? Or do we just square it and say its square is equal to a square?

[@tajbibishamim8085]

14.57 should be sq.rt. of x shd be taken as denominator and solve left hand side and you get 9/6 which becomes 3/2=6 sort. x Divide both side by 6 and you get 1/4=sq.rt.x so the answer is 1/16.

[@Desti_amenu]

What is the app u used

[@BORN-to-Run]

I know this is an old video, but you didn't tell us WHY we're raising the second equation to the 3rd power, rather than to the 2nd power...! @2:14

[@jin_cotl]

Um because the operation has a cube root, it shows it right there on the left. There’s a root, and it’s to the third. Cube root. So inorder to cancel the root, you need to multiply both sides by the power of three.

[@BORN-to-Run]

[@andressantana5369]

Thanks for this great video, but why do we need to foil in the third exercise? I dont get it. :(

[@bbw1979]

It’s like doing 2 digit multiplication. You multiply the ones and tens digit in one one number by the ones and tens digits it the other number 12^2 = 12*12 = (10+2)(10+2) = 100+20+20+4 = 144 The mistake that people make is like doing (10+2)^2 as 10^2+2^2=100+4=104 which as you know does not equal 144

Why is that the equation on 10:50 doesn't work? Can't the square root of 6.25 be -2.5? I thought normal radicals usually have both negative and positive roots? Isn't -2.5^2 the square root of 6.25 as well? X can be both 8 and 5.25.

[@FoodBasics4]

how would you solve this equations square root 2x - square root of x+1 = 1

[@adamabdallah2604]

Cynthia Alley you square both sides to remove the square root so you will be left with. 2x-x+1=1. Now 2x-x=1-1 2x-x=x 1-1=0. So x =0. Fill in the answer in the original equation it will be 1=1

[@zeroanims4113]

@@adamabdallah2604 hey question, can you actually square the sqrt of 2x - sqrt of x + 1 = 1 Because as far as I know you can't square two terms separated by plus sign or minus sign? (unless you're gonna foil it, which I think you didn't..?)

[@mathiuescario3057]

The square root of 6.25 is +-2.5, not just +2.5, which means 5.25 is not an extraneous solution. Just saying.

[@Kevessi]

@John nope....nope you're not.

[@n1vr132]

Yes but again he is only considering the principal root. So negatives are going to be avoided. And to actually check if the final answer works you have to substitute this to the x in the equations and this works.
