I've just made this simple cubic equation solver and I was wondering if anyone would like to give me some input, as I hope to produce a better version at some point. Enjoy!

If I remember my deterministic polynomial equation theory, I believe up to fifth-degree polynomials can be solved algebraically, in general... though by a much more complex method than fourth-degree polynomials.

It has been proved I think that you can solve up to quaratic equations algebraically, the method is very clearly shown on http://www.1728.com/quartic2.htm.

Yeah its 12^3.
Also did you know that 1728 + 1  or (1729) is the lowest number expressable by the sum of two cubes in two different ways. Namely :
10^3 + 9^3 and 12^3 + 1^3
