Formula for roots of higher polynomials?

Does anyone know of the formulas for roots of higher order polynomials (3+)?  We learned the quadratic formula in grade school but never heard of formulas for higher polynomials..  do they exist?

There's a very complicated one for cubics, and there's a super-duper complicated one for quartics. However, Niels Abel proved that no formula exists for quintics, and Evariste Galois proved that no formula exists for anything above quartics.

Just use Newton's method. It's easy, and it kicks ass.
