Combining rational expression with unlike denominators

The video tutorial explains how to simplify and factor expressions to find the least common multiple (LCM) of unlike denominators. It covers the process of factoring trinomials, applying the distributive property, and determining constraints by setting the denominator equal to zero. The tutorial emphasizes the importance of simplification and checking for common factors before solving the problem.
