This section regroups several methods for deriving Cardano's formula. This method is due to Scipione del Ferro and Tartaglia, but is named after Gerolamo Cardano who first published it in his book Ars Magna (1545). This method applies to a depressed cubic t + pt + q = 0. The idea is to introduce two variables u and v such that u + v = t and to substitute this in the depressed cubic, giving WebThe cubic equation formula is used to represent the cubic equation.
