I think it's D

simplify. x^2-16x+64/x2-64

A) -1
B) x-1/x+1

D) x-8/x^2-64

I started working it out and got stuck with -16x+64/-64. I'm not sure what to do next.

Answer 1

1) u need factor out to simpify it
(x^2+8x)/x^2 = x(x+8)/x^2 = ...
2) (x^2-16x+64)/(x^2-64) = (x-8)(x-8)/(x-8)(x+8) = ... (cancel out the similar terms)
