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?

Actually, I called you a tit because, seeing your pretentious posting history, you're basically a tit. Also:
"Making the 4th power of complexity the demarcation point just seems like an arbitrary thing."
Yes, I'm sure years of formal mathematical theory went into proving that something they made the hell up was true.
