Answer
$(3x-2)(x+1)$
Work Step by Step
Grouping the first and second terms and the third and fourth terms, the given expression is equivalent to
\begin{array}{l}\require{cancel}
3x^2-2x+3x-2
\\\\=
(3x^2-2x)+(3x-2)
.\end{array}
Factoring the $GCF$ in each group results to
\begin{array}{l}\require{cancel}
x(3x-2)+(3x-2)
.\end{array}
Factoring the $GCF=
(3x-2)
$ of the entire expression above results to
\begin{array}{l}\require{cancel}
(3x-2)(x+1)
.\end{array}
