question\nfactor the expression completely.\n-30 - 21x

Explanation:

Step1: Find the GCF of -30 and -21

The GCF of 30 and 21 is 3. Since both terms are negative, the GCF is -3.

Step2: Factor out the GCF

We divide each term by -3. $\frac{-30}{-3}=10$ and $\frac{-21x}{-3} = 7x$. So, $-30 - 21x=-3(10 + 7x)$.

Answer:

$-3(10 + 7x)$
