You can put this solution on YOUR website!
If x=1 is a solution and x=-8 is a solution, then
the quadratic equation looks like.
f%28x%29=%28x-1%29%28x%2B8%29
because
x-1=0 for x=1
and
x%2B8=0 for x=-8
f%28x%29=%28x-1%29%28x%2B8%29
f%28x%29=x%2Ax%2Bx%2A8%2B%28-1%29%2Ax%2B%28-1%29%288%29
f%28x%29=x%5E2%2B8x-x-8
f%28x%29=x%5E2%2B7x-8
