From Wikipedia, the free encyclopedia
A cubic formula is one of several methods to find the roots of a cubic function , where f(x) = 0. The most well known method is Cardano's formula for the solutions to a depressed cubic equation
where the
component is reduced away, which has solutions at

However, there are several solutions, which make use of algebra, trigonometry, and/or geometry to arrive at the roots of the cubic function.
