Answer: <em>x=9,-1</em>

Step-by-step explanation:

<em>First, we are gonna start out with finding two numbers that multiply to equal -9 and add up to equal -8</em>

<em>Those numbers would be -9 & 1</em>

<em>-9+1=-8</em>

<em>-9x1=-9</em>

<em>Now we have </em>

<em>(x-9)(x+1)</em>

<em>x-9=0   x+1=0</em>

<em>   +9 +9   -1  -1</em>

<em>x=9      x=-1</em>
