Simplify a rational expression by factoring

The video tutorial explains how to simplify rational expressions by identifying values that make the expression undefined, such as division by zero. It demonstrates factoring techniques for both the numerator and denominator, including finding common factors and using the zero product property to determine excluded values. The tutorial emphasizes the importance of excluding values that make the denominator zero and provides a step-by-step approach to simplifying complex expressions.
