How to Solve Cubic Equations
On the last Pythagorean Theorem Day (12/16/20), I was thinking about the solution of a Cubic Equation (the one in the picture). Do you know that they do not teach students how to solve the cubic equations whose formula has been known to us for about 500 years? But, do you know the reason? It is because it is not that simple to apply. It requires the knowledge of complex algebra. If you check online there is a lot of information, however it is all spread around in bits and pieces. In this article, I have shown how to derive the cubic formula, together with the introduction of basic complex algebra topic, and I present the solutions to several different problems by following a step by step procedure. In this regard, this will serve as a good source for those who would like to learn about the cubic formula and how to use it.
