Answer
$3 \left( 6x+5 \right)$
Work Step by Step
$\bf{\text{Solution Outline:}}$
Get the $GCF$ of the given expression, $
18x+15
.$ Divide the given expression and the $GCF.$ Express the answer as the product of the $GCF$ and the resulting quotient.
$\bf{\text{Solution Details:}}$
The $GCF$ of the terms is $
3
$ since it is the highest number that can evenly divide (no remainder) all the given terms. Factoring the $GCF=
3
,$ the expression above is equivalent to
\begin{array}{l}\require{cancel}
3 \left( \dfrac{18x}{3}+\dfrac{15}{3} \right)
\\\\=
3 \left( 6x+5 \right)
.\end{array}
