Factor 9z+18 using the GCF

3 answers

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

  1. The terms are \(9z\) and \(18\).
  2. The GCF of the coefficients \(9\) and \(18\) is \(9\).
  3. We can factor out \(9\) from each term:

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

Now, we can factor out the \(9\):

\[ 9(z + 2) \]

Thus, the factored form of \(9z + 18\) is:

\[ 9(z + 2) \]

What’s the answer

The factored form of \(9z + 18\) using the greatest common factor (GCF) is:

\[ 9(z + 2) \]
