Answer:

2·(a^2 + b^2) = (a + b)^2

2·a^2 + 2·b^2 = a^2 + 2·a·b + b^2

a^2 + b^2 = 2·a·b

a^2 - 2·a·b + b^2 = 0

(a - b)^2 = 0

a = b

What is the answer to -3/4 (2)(-6) in fraction form

nasty-shy [4]

I'm assuming the question looks like this?

$\frac{-3}{4} (2)(-6)$

If so then the answer should be:

$\frac{-3}{4} (2)(-6)=\frac{-3}{4} (-12)=9$

Hope this helps!
