Question

Factor the expression below.

X2 + 16x + 64
O A. (X + 8)(x + 8)
O B. (x - 4)(x - 16)
O C. (x-8)(x-8)
O D. (x + 4)(x + 16)

Answer 1

A. (x+8)(x+8)

Explanation:

F: x*x=x^2

O: x*8=8x

I: 8*x=8x

L: 8*8=64

x^2+8x+8x+64 = x^2+16x+64

Answer 2

x^2 + 16x + 64
x + x = 16
x^2 = 64
Therefore x = 8
(X + 8)(x + 8)

Solution: A
