# What is the difference of squares that have a factor of x + 8? Complete the expression x^{2} - ….

**Solution:**

We know that

a^{2} - b^{2} = (a + b)(a - b)

One of the factors is x + 8

So the other factor is x - 8 from the formula

(x + 8)(x - 8) = x^{2} - 8^{2} = x^{2} - 64

Therefore, the difference of squares that have a factor of x + 8 is x - 8. The expression is x^{2} - 64.
