Answer

The solution set is $\left\{0, 9\right\}$.

Work Step by Step

Factor out the GCF, which is $x$, to obtain: $x(x-9)=0$ Use the Zero-Product Property by equating each factor to zero and then solving each equation to obtain: $\begin{array}{ccc} &x=0 &\text{ or } &x-9=0 \\&x=0 &\text{ or } &x=9 \end{array}$ Thus, the solution set is $\left\{0, 9\right\}$.
