The video tutorial demonstrates how to factor the quadratic equation x^2 - 9x - 22. It begins by setting up a skeleton equation and determining the signs based on the terms. The instructor then finds factors of the last term that sum to the middle term, using 2 and 11. The factorization is verified using the FOIL method, ensuring the original equation is obtained. Finally, the video shows how to solve for x, finding values that make the equation zero, and concludes with a summary of the process.
