I tried solving a polynomial equation using Microsoft math 3.0. The program used a formula involving Trig, a form of cosine formula. I was wondering if anyone could do me the favor of writing me the formula and explain it. Thanks.

Oh, thanks Siron. I've solved it, can solve it but what I wanna know is if there is a formula that can solve them just like the quadratic formula. Is there a polynomial formula like the one used at Online Equation Solver
