Factoring Quadratic Equations and Solutions

The video tutorial demonstrates how to factor the quadratic equation x^2 - x - 12 = 0. It begins by setting up a skeleton equation and adding appropriate signs. The instructor then identifies factors of -12 that sum to -1, and verifies the factorization using the FOIL method. Finally, the video shows how to find the solutions for x that satisfy the equation, confirming the solutions by substitution.
