Question

(X+8)(x-8) if necessary combine like terms

Answer 1

Answer:

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

Answer 2

Answer:

$x^2-64$

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 $x^2-64$
