Step 1

1 of 5We must solve the given equation, and then check our solution.

$x^2 = -15 + 8x$

Rewrite the given equation:

$\blue{x^2} -8x+15=0$

Find two integers which multiplied give $\blue{x^2}$.

The factors are $\bold{x} \cdot \bold {x}$

Continue factoring:

$\begin{align*} x^2-8x+15 &= 0\\ (\bold{x}+\_\_)(\bold {x}+\_\_)&=0 \end{align*}$
