You can put this solution on YOUR website!
If x=1 and x=-8 are zeros for a quadratic equation, then they satisfy,
x-1=0
x%2B8=0
The simplest quadratic equation would be the two left hand sides multiplied together.
%28x-1%29%28x%2B8%29=0
Using the FOIL method we can expand the left hand side,
%28x-1%29%28x%2B8%29=0
x%5E2%2B8x-x-8=0
x%5E2%2B7x-8=0
