Answer
$16z^2x(zx-2)$
Work Step by Step
$\bf{\text{Solution Outline:}}$
To factor the given expression, $
16z^3x^2-32z^2x
,$ factor the $GCF.$
$\bf{\text{Solution Details:}}$
The $GCF$ of the terms in the given expression is $
16z^2x
,$ since it is the greatest expression that can divide all the terms evenly (no remainder.) Factoring the $GCF$ results to
\begin{array}{l}\require{cancel}
16z^2x(zx-2)
.\end{array}
