Bot GPT 4-o mini To factor the expression \( 9z + 18 \) using the greatest common factor (GCF), we first identify the GCF of the terms in the expression.
- Identify the coefficients: The coefficients are 9 and 18.
- Find the GCF: The GCF of 9 and 18 is 9.
- Factor out the GCF: We factor out 9 from each term.
So, we can rewrite the expression as:
\[ 9z + 18 = 9(z + 2) \]
Thus, the factored form of \( 9z + 18 \) is \( 9(z + 2) \).
