Question

2(x+h)^2
its 2x^2 + 4xh + 2h^2 right?
think teacher wrote wrong thing on answer key

Answer 1

So you would expand (x + h)^2 first, and get

\[x^2*2xh*h^2\]

And then you would multiply everything by 2 and get

\[2x^2*4xh*2h^2\]

Yep, I'm 99% sure you got it right :)

Answer 2

Haha sounds good, answer key is wrong then lol, appreciate the help
