Factoring Quadratic Equations and Verification

The video tutorial demonstrates how to factor the quadratic equation x^2 - 12x + 36 = 0. It begins by setting up a skeleton equation and identifying the signs based on the middle term. The factors of the last term are found to match the middle term, leading to the equation being factored as (x-6)(x-6). The FOIL method is used to verify the factorization. Finally, the video shows how to solve for X, confirming that x = 6 satisfies the equation. The quadratic formula is also mentioned as an alternative method.
