### Lesson Excerpt:

Multiplying Rational Expressions with Binomials and Trinomials

- "The next type of problem that we are going to be working on are rational expressions that have binomials and trinomials in them. Up until this point, we have been multiplying rational expressions with monomials. Now we are moving to the more challenging problems. A lot of the steps are going to remain the same, but we are going to need to do a little bit more work before we can multiply them. Let's look at an example so I can explain further."
- On Board: x + 3 . 6y
2y x2 + 8x + 15

- "The first thing that we are going to do when working on this problem is look to see if there is anything that needs to be factored."
