To factor the expression \( 9z + 18 \) using the greatest common factor (GCF), follow these steps:
1. Identify the GCF of the terms in the expression.
- The coefficients are 9 and 18. The GCF of 9 and 18 is 9.
- The variable term is \( z \) (which is only present in the first term).
2. Factor out the GCF from the expression:
\[
9z + 18 = 9(z) + 9(2)
\]
3. This can be rewritten as:
\[
9(z + 2)
\]
So, the factored form of \( 9z + 18 \) is \( 9(z + 2) \).
