Deriving the Cubic Formula | Cubic Formula Proof

In this video, I prove/derive the cubic formula from the original cubic equation. This is a full mathematical proof using Cardano's method of proving the cubic. This is similar to the quadratic equation, just more complex. The goal was to create a simple, quick, concise and full explanation of the proof. Vieta's Theorem and algebra were used.
