Factor 9z+18

using the GCF.(1 point)

1 answer

To factor the expression \( 9z + 18 \) using the Greatest Common Factor (GCF):

  1. First, identify the GCF of the coefficients 9 and 18. The GCF of 9 and 18 is 9.
  2. Next, factor out the GCF from the expression:

\[ 9z + 18 = 9(z + 2) \]

So, the factored form of the expression \( 9z + 18 \) is \( 9(z + 2) \).
