One can hardly believe that there is still something to be said about cubicequations. To dodge this doubt, we will instead try and say something aboutSylvester. He doubtless found a way of solving cubic equations. As mentioned byRota, it was the only method in this vein that he could remember. We realizethat in the generic case Sylvester's magnificent approach aimed at reducedcubic equations boils down to an easy identity expressing a cubic polynomial asa sum of two third powers of linear forms. This leads to Cardano's formula forcubic equations involving the third roots of unity.
