question help: video ebook

Explanation:

Step1: Identify difference of squares

Recognize $y^2 - 144$ as $a^2 - b^2$, where $a=y$, $b=12$ (since $12^2=144$).

Step2: Apply difference of squares formula

Use $a^2 - b^2=(a-b)(a+b)$.
<Expression>
$y^2 - 144=(y-12)(y+12)$
</Expression>

Answer:

$(y-12)(y+12)$
