help?

anonymous · Answer

I cant use a calculator for this problem

anonymous · Answer

four cheap and easy points can be obtained by setting x=-1, 0, 1, 2

anonymous · Answer

if this is a calc problem, then it would be worth it to FOIL the above binomials.  three of the above points are the x intercepts and one point, x=0, is the y intercept.
