Part 1/5:

Understanding the PQ Substitution Method for Cubic Functions

The process of solving cubic equations can often seem daunting, especially when you come across terms that complicate the equation, like the (x^2) term. However, one effective method known as the PQ Substitution Method aids in simplifying and solving these cubic functions, allowing for greater clarity and ease in finding solutions.

The Aim of PQ Substitution

The primary goal in using the PQ substitution method is to eliminate the (x^2) term in a cubic function. When we have a general cubic equation structured as:

[

a x^3 + b x^2 + c x + d = 0
