Solve by factoring when a=1

The video tutorial explains how to solve quadratic equations by converting them into intercept form. It introduces the diamond method for factoring, specifically when the leading coefficient is 1. The instructor demonstrates how to apply this method by identifying two numbers that multiply to a given constant and add to a given coefficient. The quadratic is then factored, and the zero product property is used to find the solutions for X.
