Factor the given expression. x^2+16x+64 a) (x + 8)2 b.) (x + 8)(x − 8) c. ) (x + 4)2 d.) (x + 16)(x + 4)

A. (x+8)² is the correct answer.

First, you had to break the expression into their groups.

And it gave us ⇒

Then, you had to factor it out from x²+8x=x(x+8).

Next, factor you had to factor it out from 8x+64=8(x+8)

And it gave us ⇒

You can also keep the factor of their common term of (x+8).

And it gave us ⇒

Finally you had to refine and it gave us the final answer is.

And it gave us ⇒
