SolveCubic[ <Cubic Polynomial> ]: Solves a given cubic polynomial and returns a list of all solutions.; Example:
SolveCubic[x³ - 1] yields { 1, \frac{1}{2} (\sqrt{3} i -1) , \frac{1}{2} (\sqrt{3} (-i) -1) } .

Note:

You will often need to simplify your answers manually, e.g. SolveCubic[x³ + x² + x + 1].
