How do we add fractions expressions for rational expressions

This video tutorial explains how to add and subtract rational expressions, focusing on polynomials. It begins with a review of adding and subtracting simple fractions, emphasizing the importance of common denominators. The tutorial provides examples of both operations, demonstrating how to find the least common multiple and simplify results. The concepts are then applied to rational expressions with polynomials, preparing students for more complex problems.
