Hey there! You need to solve the equation ax^2+bx+c=0 ya?
OpenStudy (steve816):
Well, f(x) has to equal to 0, so look at the second column on the table, and go down until you find 0! Look at the x value when f(x) = 0, and you will have the answer!
OpenStudy (enricoanders):

Careful! -8 is not the only solution. Since it is a quadratic, there should be 1 more. Find it?
OpenStudy (enricoanders):
so 40?

Nope, it would be -5 and -8!
