factor completely.
$x^2 - 25$

Explanation:

Step1: Identify the formula

The expression $x^2 - 25$ is a difference of squares, which follows the formula $a^2 - b^2=(a + b)(a - b)$.

Step2: Apply the formula

Here, $a = x$ and $b = 5$ (since $25 = 5^2$). Substituting into the formula, we get $(x + 5)(x - 5)$.

Answer:

$(x + 5)(x - 5)$
