Factoring Quadratic Equations Concepts

The video tutorial demonstrates how to factor the quadratic equation x squared minus 11x plus 24. It begins by setting up a skeleton equation and determining the signs based on the middle term. The instructor then finds factors of the last term, 24, that add up to the middle term, 11. The factors are used to complete the skeleton equation. The solution is verified using the FOIL method. Finally, the instructor solves for the values of X that make the equation equal to zero, confirming the results with the quadratic formula.
