The Cubic Equation

Every good history of math book will present the solution to the cubic equation and tell of the events surrounding it.The book will also mention, usually without proof, that in the case of three distinct roots the solution must make a detour into the field of complex numbers.In these notes we prove this result and also discuss a few other nuances often missing from the history books.
