## Main Question or Discussion Point

Hi,

I use the [tex]\frac{-b \ \pm \ \sqrt{b^2 - 4ac}}{2a}[/tex] formula to factoring the quadratic equation. Can anyone tell me how to factoring the cubic equation? Usually I use the division method to factoring higher order than quadratic equation such as cubic, etc., by trial, one-by-one.
