I've been trying to derive general solutions for cubic roots, i.e. the general solutions of (will Latex just work?)(adsbygoogle = window.adsbygoogle || []).push({});

$ax^3+bx^2+cx+d=0$

I do not want to be shown the solutions - but does anyone know what direction to go in to achieve this?

I thought I'd found solutions at one point but they relied on one of the solutions (the simplest in form) being $\sqrt{-c/a}$ and that doesn't appear to be true!
