Fraction Operations and Simplification

The video tutorial explains how to simplify a complex fraction by first finding the difference between two rational expressions and then dividing by a variable. It covers finding a common denominator, combining numerators, and simplifying expressions. The tutorial also demonstrates converting division into multiplication using reciprocals and provides guidance on entering the simplified form into an online system.
