In this video, we'll explore how to solve third-degree polynomial equations using Cardano's method. We'll start with depressed cubic equations and learn how to transform any cubic equation into its depressed form. Then, we'll use the cubic formula to find a solution and finally, translate that solution back to the original equation, allowing us to solve any cubic equation.
