Question

What is a difference of squares that has a factor of x + 8?

Answer 1

here a = x and b = 8, thus if x + 8 is a factor, then x - 8 is also a factor.. (x + 8)(x- 8) <-- expand this out using difference of squares rules.

Answer 2

Answer: In other words, the answer is

(x+8) (x-8) (or) x^2 - 64
