Factor 9z + 18 using the GCF. (1 pc

Answer 1

To factor out the GCF (Greatest Common Factor) of the expression 9z + 18, we need to find the largest number that evenly divides both terms.

First, let's look at the coefficients (numbers) of the terms. The coefficients of 9z and 18 are 9 and 18, respectively.

The GCF of 9 and 18 is 9, since 9 is the largest number that divides both 9 and 18 evenly.

Then, let's consider the variable part. Both terms have the variable z, so we can include it in the factored expression.

Therefore, factoring out the GCF of 9z + 18, the expression becomes:

9z + 18 = 9(z + 2)

The final factored form of 9z + 18 is 9(z + 2).
