Factoring Quadratic Equations and Solutions

The video tutorial demonstrates how to factor the quadratic equation x^2 - 12x + 20 = 0. It begins by setting up a skeleton equation and adding appropriate signs. The instructor then identifies factors of the constant term that sum to the middle term. The factorization is verified using the FOIL method. Finally, the video shows how to solve for the values of X that satisfy the equation, confirming the results with the quadratic formula.
