The video tutorial explains how to solve a quadratic equation by setting it to zero and checking its factorability using the a*C method. It involves listing factors of 12 to find the correct pair that adds to -7. The equation is then rewritten, and the box method is used to solve it. Finally, the zero product property is applied to find the solutions, which are x = 2/3 and x = 1/2.
