Lesson Summary:

In this lesson, students will learn how to factor four-term polynomials by grouping. The instructor explains that whenever there are four terms, it is best to check if factoring by grouping is possible before trying to use the trinomial method. The instructor then walks through two examples and explains how to factor out common terms to arrive at the final answer. The lesson emphasizes the importance of grouping terms correctly and checking the factored expressions by multiplying them back together.
