y^3 + y^2 - 3y - 3

I've just gotten transferred to this alien math class in my new school. I just need someone to help me factor this equation so I can get a feeling of what I should do.

So far I've gotten as far as: y(y^2+y-3)-3

I don't think I'm going the right direction, but if I am, what next? Please help ;_;
