Hi,

I think I heard of formulae that directly get you the roots of a degree 3 polynomial. I mean, like the ones of a degree 2 which are

(-b + or - (b^2 - 4 ac)^1/2) / 2a

I'm posting this question because I need them like that, in symbols. I don't care about the numerical value since I can get it using my calculator.

Thanks very much.
