Understand undefined values when trying to simplify a rational expression

The video tutorial explains the process of factoring expressions and the importance of the division property in simplifying expressions. It emphasizes that terms can only be divided out when separated by multiplication. The tutorial also covers domain restrictions, highlighting values that make the denominator zero, and concludes with a summary of the key points discussed.
