Hello,

I'm trying to help my brother with a math problem, but I just haven't done this stuff in quite a while so I don't even know where to start. I'd appreciate any assistance!

Cheers.

Find the zeros for the function f(x) = ax^3 + bx^2 -106x + d, given that f(-1) = 343, f(2) = 40, and f(3) = -33.
