Question

uugh i still dont understand square roots

Answer 1

What's your question about them?

Answer 2

Or where are you stuck?

Answer 3

Just post the actual question you're working on.

Answer 4

I think what most people have a problem with is the +-sqrt()
so lets think about the square root of 4. what number(s), if we multiply by itself, will be 4? well 2*2 = 4 and (-2)*(-2)=4 so the square root of 4 (sqrt(4)) = +-2 that is 2 and -2 are the square roots of 4

so if we have y^2 = x and we are trying to solve for y ( get y alone on the left hand side) we have

y^2 = x
so
y = sqrt(x) and y = -sqrt(x) (we write this as +-sqrt(x))

hope this helps.
