How to simplify a rational expression and write the excluded values

The video tutorial explains how to simplify trinomials by factoring them into products of their factors. It demonstrates the application of the division property once expressions are rewritten as products. The tutorial also covers the concept of excluded values and removable discontinuities, emphasizing the importance of identifying values that make the denominator zero.
