Answer:

C. x^2 + 8x +16

Explanation:

(x+4)(x+4)


x^(2)+4x+4x+16


x^(2)+8x+16

A. x^2 + 4x + 16 -> No! they did not add the two 4x

B. x^2 + 8x^2 + 16 -> No! they added the two 4 but they seem to have multiple the xs

C. x^2 + 8x + 16 -> Yes! it's the same results we got when we solve it

D. 2x + 8x +16 -> No! they added the two Xs.
