SOLUTION: If x = 1 and x = -8, then form a quadratic equation whose solution are these values. Would I begin by saying y=(x+1)*(x-8)=0. I am completely lost.

You can put this solution on YOUR website!
just reverse the process..if you have x=1 then what does it take to get x to equal zero.....subtract 1 from each side..x-1=0 do the same for x=-8...only this time you have to add 8...x+8=0

so we have %28x-1%29%28x%2B8%29=0 orx%5E2%2B8x-x-8=0 or x%5E2%2B7x-8=0
