The video tutorial explains how to solve a quadratic equation by recognizing patterns and using substitution. It begins with setting up the equation and identifying a simpler method by observing the structure. The tutorial then demonstrates substituting a part of the equation with a variable P, simplifying the equation, and solving for P. Finally, it translates the solutions for P back to the original variable X, providing a more efficient approach than traditional methods.
