Answer
$3x^2-23x-8$
Work Step by Step
Make a table.
$\ \ \ \ \ \ \ \ \underline{|\ \ \ \ \ \ \ x\ \ \ \ \ \ |\ \ \ \ \ \ -8\ \ \ \,\ \ |}$
$\ \ \ 3x\ |\ \ \ \ \ 3x^2\ \ \ \ |\ \ \ -24x\ \ \ \ \ |$
$\ \ \ \ 1\ \ |\ \ \ \ \ \ \ x\ \ \ \ \ \ |\ \ \ \ \ \ \ -8\ \ \ \ \ |$
The product is
$3x^2-24x+x-8$
Combine like terms.
$3x^2-23x-8$
