Polynomial Operations and Factoring

The video tutorial covers the basics of polynomials, including their addition, subtraction, and multiplication. It introduces the FOIL method for multiplying binomials and explains how to factor polynomials, focusing on quadratic expressions. The tutorial uses a generic rectangle method to simplify the factoring process and highlights the importance of identifying like terms.
