Lesson Excerpt:

Factoring Binomials

- "The next thing that we are going to learn about is how to factor a binomial. We just reviewed factoring monomials. Remember, that monomial is talking about one term, when we are working with binomials, we will be working with two terms that are being added or subtracted together."
- "In the past, we have been multiplying binomials. When we multiplied binomials, we worked with the distributive property to get rid of the parentheses and multiply out the terms. Here is an example."
- On Board: 3(2x + y) = 6x + 3y
- "In this problem, we multiplied or distributed the 3 with both of the terms inside the parentheses and ended up with our final binomial. Does everyone remember these problems?"
