Question

factor using gcf or monomial factoring: 2x + 18; cannot be factored; 2(x + 8); 2(2x + 9); 2(x + 9)

Explanation:

Step1: Find GCF of terms

The terms are $2x$ and $18$. The greatest common factor (GCF) of 2 and 18 is 2.

Step2: Factor out the GCF

Divide each term by the GCF and write as a product:
$2x + 18 = 2(x) + 2(9) = 2(x + 9)$

Answer:

2(x + 9) (the option in the teal/blue square)
