question
factor the expression completely.
$-63x^5 + 72$

Explanation:

Step1: Factor out the GCF

First, find the greatest common factor (GCF) of $-63x^5$ and $72$. The GCF of $63$ and $72$ is $9$, and we can also factor out a negative sign for simplicity. So we factor out $-9$ from both terms.
$-63x^5 + 72=-9(7x^5 - 8)$

Answer:

$-9(7x^5 - 8)$
