Factoring out the GCF from the denominator to help you simplify your rational expression

The video tutorial discusses the process of factoring, emphasizing the importance of identifying the Greatest Common Factor (GCF) before using other methods like trinomials. The instructor provides a detailed example, demonstrating how to factor a polynomial by first extracting the GCF. The tutorial concludes with a simplified version of the example, reinforcing the concept of equivalence in expressions.
