Combining rational expression with like denominators

The video tutorial explains how to combine and simplify rational expressions. It begins by discussing the conditions under which rational expressions can be combined, focusing on the importance of having the same denominators. The tutorial then examines the numerators, highlighting that terms must have the same factors to be combined. The process of simplifying expressions is demonstrated, with an emphasis on identifying when further simplification is not possible. The tutorial concludes by presenting the final answer and discussing potential restrictions, such as ensuring that X does not equal zero.
