Factor any difference of two squares, or state that the polynomial is prime. Assume any variable exponents represent whole numbers.

x2 - 100

To factor the difference of two squares, we can use the following formula:

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

In this case, we have x^2 - 100. We can rewrite 100 as 10^2, so the expression can be written as:

x^2 - 10^2

Now we can apply the formula:

(x + 10)(x - 10)

Therefore, the factored form of x^2 - 100 is (x + 10)(x - 10).
