Answer
$x=\left\{ 0,11 \right\}$
Work Step by Step
Equating each factor to zero (Zero Product Property), then
\begin{array}{l}\require{cancel}
8x=0
\\\\\text{OR}\\\\
11-x=0
.\end{array}
Solving each equation results to
\begin{array}{l}\require{cancel}
8x=0
\\\\
x=\dfrac{0}{8}
\\\\
x=0
\\\\\text{OR}\\\\
11-x=0
\\\\
-x=-11
\\\\
x=11
.\end{array}
Hence, the solutions are $
x=\left\{ 0,11 \right\}
.$
