Factor 9z + 18 usually GCF

Answer 1

To factor the expression $9z+18$ using the greatest common factor (GCF), first identify the GCF of the terms in the expression.

The terms are:

• $9z$
• $18$

The GCF of $9$ and $18$ is $9$.

Now, factor out the GCF from the expression:

$$9z+18=9(z+2)$$

So, the factored form of $9z+18$ is:

$$9(z+2)$$
