Simplifying a trigonometric expression by factoring out the GCF

The video tutorial covers the process of factoring mathematical expressions, starting with simple algebraic terms and progressing to more complex polynomials. It then applies these factoring techniques to trigonometric expressions, using trigonometric identities to further simplify the expressions. The tutorial emphasizes the importance of identifying the greatest common factor (GCF) and checking the factored form using the distributive property. The video concludes with a discussion on simplifying trigonometric expressions using Pythagorean identities.
