Lesson Excerpt:

- "In our past lessons, we have been factoring different types of polynomials. We started off factoring monomials and binomials. Then, we moved on to factoring polynomials using greatest common factors."
- "Here is an example to review."
- On Board: 12x2y2 - 18x3 + 2y2 - 6y4
- "Now when working on this problem, the first thing that we can see is that this is a polynomial with four terms in it. When we have a polynomial with four terms, we want to look and see if we can group some of the like terms together. In this case, we have some terms to work with. Here are the like terms grouped together."
- On Board: 12x2y2 - 18x3 + 2y2 - 6y4
- "Once we have grouped the like terms, we can go ahead and factor each section of the polynomial. Who can go ahead and factor this polynomial for us?"
