Polynomials: Multiplying Polynomials (Part 1)

Lesson Procedure:

Print the classroom lesson plan and worksheet questions (see below).

Lesson Excerpt:

- “In the past several lessons, we have been multiplying monomials with binomials and trinomials using the distributive property. Because we were multiplying monomials with binomials and trinomials, there was only one term (the monomial) to distribute with the others. Here is an example of what I am talking about.”
- On Board: (-3x)(4x + 6)
- “When we worked on these types of problems, we multiplied the –3x by both of the terms in the binomial and came up with a final answer. In this case, what is the final answer to this problem?”
- Use a student volunteer. Student answer = -12x2 – 18x
- “Good, now we are going to be moving on from these problems. Today we are going to learn about how to multiply two binomials together.”
