You can
put this solution on YOUR website!in a quadratic equation, for x, you solve for the value that would make an expression zero. So if x=1 and x= -8, just move backwards.
For positive x's
(x-b)=0
For negative x's
(x+b)=0
plug in your x's
(1-b)=0
(-8+b)=0
Solve for b's
b=1
b=8
So the original equation was
(x-1)(x+8)=0
