x² - 64

Step-by-step explanation:

Given

(x + 8)(x - 8)

Each term in the second factor is multiplied by each term in the first factor, that is

x(x - 8) + 8(x - 8) ← distribute both parenthesis

= x² - 8x + 8x - 64 ← collect like terms

= x² - 64

x^2-64

Step-by-step explanation:

1) x*x=x^2

2) x*(-8)=-8x

3) 8*x=8x

4) 8*(-8)=-64

5) x^2-8x+8x-64= x^2-64

6) So the answer is x^2-64
