Simplifying a rational expression by factoring

The video tutorial explains how to handle mathematical expressions with terms separated by addition or subtraction, emphasizing the common mistake of misapplying exponent rules. It introduces the concept of rewriting expressions as multiplication through factoring, covering techniques like finding the greatest common factor (GCF) and the difference of squares. The tutorial also demonstrates factoring trinomials using the box method and concludes with simplifying expressions by dividing out common terms.
