Simplifying a rational expression by factoring

The video tutorial explains how to factor expressions in both the numerator and denominator. It covers identifying the greatest common factor (GCF) and using the difference of squares method for factoring. The tutorial also discusses restrictions on variable values to avoid division by zero and demonstrates the final simplification of the expression while maintaining these restrictions.
