RE: Cubic Formula Proof Step 2: Applying Vieta's Substitution to Obtain a Quadratic Equation

Part 1/5:

Solving Cubic Equations Using V's Substitution

In mathematics, solving cubic equations can often be quite complex. However, applying V's substitution offers a systematic approach to simplify this process. In this article, we will delve into the method of transforming a cubic equation of the form ( y^3 + py + Q = 0 ) into a simpler quadratic equation, enabling us to find the roots of the cubic more easily.
