-
1+
x ||

Answer 1

To expand and combine like terms, use the FOIL method. (x + 8)(x - 8) simplifies to x^2 - 64.

Step-by-step explanation:

To expand and combine like terms, we need to apply the FOIL method. FOIL stands for First, Outer, Inner, and Last. We multiply the first terms, the outer terms, the inner terms, and the last terms respectively.

In this case, when we multiply (x + 8) and (x -8), the first terms are x * x, the outer terms are x * -8, the inner terms are 8 * x, and the last terms are 8 * -8.

Simplifying the multiplication gives us x^2 - 64.
