Question

how does (x+h)(x^2+2xh+h^2)=2x^2+4xh+2h^2

Answer 1

2= x + h

Answer 2

Don't understand why but I see how that would work. so why does x+h=2?

Answer 3

(x+h)(x^2+2xh+h^2)=2x^2+4xh+2h^2
factor out 2 on right side
(x+h)(x^2+2xh+h^2)= 2(x^2+2xh+h^2)
divide both side by (x^2+2xh+h^2)
so (x+h)=2

Answer 4

thank you!

Answer 5

you're welcome. :)

Answer 6

So if you have (x+h)(x^2+2xh+h^2) how do you get the answer?
