Factoring to help us simplify a basic rational expression

The video tutorial reviews the rules of exponents and introduces simplifying expressions by factoring. It emphasizes the importance of understanding restrictions, particularly when a value makes the denominator zero. The tutorial guides students through the process of identifying restrictions and simplifying expressions while considering these restrictions.
