Question

factor.
$w^2 - 25$

Explanation:

Step1: Identify difference of squares

Recognize $w^2 - 25$ as $w^2 - 5^2$, which fits the difference of squares pattern $a^2 - b^2$.

Step2: Apply difference of squares formula

Use the identity $a^2 - b^2 = (a+b)(a-b)$, where $a=w$ and $b=5$.
<Expression>
$w^2 - 5^2 = (w+5)(w-5)$
</Expression>

Answer:

$(w+5)(w-5)$
