Factoring a third degree polynomial with four terms by grouping

The video tutorial explains how to factor polynomials with four terms using the method of grouping. It begins by introducing the concept and rationale behind factoring by grouping. The instructor then demonstrates how to group the first two and last two terms, factor out common elements, and finally combine the results to achieve a fully factored polynomial. The tutorial emphasizes recognizing shared factors and systematically applying the technique to simplify expressions.

Explain the significance of factoring out (X - 5) in the process described.

What are the final factors of the polynomial after completing the factoring process?
