$$(x-3^2)(x-5) = 0$$
Answer
$$ \begin{matrix}x_1 = 5 & x_2 = 9 \\[1 em] \end{matrix} $$
Explanation
$$ \begin{aligned} (x-3^2)(x-5) &= 0&& \text{simplify left side} \\[1 em](x-9)(x-5) &= 0&& \\[1 em]x^2-5x-9x+45 &= 0&& \\[1 em]x^2-14x+45 &= 0&& \\[1 em] \end{aligned} $$
$ x^{2}-14x+45 = 0 $ is a quadratic equation.
