Answer
$x=\left\{ 0,10 \right\}$
Work Step by Step
Factoring the given equation, $
x^2-10x=0
,$ results to
\begin{array}{l}\require{cancel}
x(x-10)=0
.\end{array}
Equating each factor to zero (Zero Product Principle), then the solutions to the equation, $
x(x-10)=0
,$ are
\begin{array}{l}\require{cancel}
x=0
,\\\\\text{OR}\\\\
x-10=0
\\\\
x=10
.\end{array}
Hence, $
x=\left\{ 0,10 \right\}
.$
