Factoring Quadratic Equations Concepts

The video tutorial explains how to factor the quadratic equation x^2 - 6x + 9. It begins by setting up a skeleton equation and determining the signs based on the middle term. The tutorial then finds the factors of the last term, ensuring they add up to the middle term. The factorization is verified using the FOIL method. The video also demonstrates solving for x to make the equation equal zero and concludes with simplifying the expression to x - 3 squared.
