Mastering Binomial Expansion

Mastering Binomial Expansion

Learning Objective

Understand and master the technique of expanding products of two or more binomials.

What do you already know about expanding binomials?

What are Binomials?

A binomial is a polynomial with two terms. For example, (x + 3) or (2y - 5).

Expanding Binomials

Expanding a binomial means to multiply it out. For example, (a + b)(c + d) = ac + ad + bc + bd.

Product of Two Binomials

Expanding the product of two binomials involves using the distributive property to multiply each term of the first binomial by each term of the second binomial.

Interactive Example 1

Expand (x + 2)(x - 3) = x^2 - x - 6.

Expanding Three Binomials

Expanding three binomials involves systematically multiplying each term of each binomial by each term of the other binomials.

Interactive Example 2

Expand (a + b)(c - d)(e + f) = ace + acf - ade - adf + bce + bcf - bde - bdf.

Expanding Four Binomials

Expanding four binomials follows the same pattern of systematically multiplying each term of each binomial by each term of the other binomials.

Interactive Example 3

Expand (p + q)(r - s)(t + u)(v - w).

Feedback

Provide feedback on the lesson and express any concerns or suggestions.

Write down 3 things you learned in this lesson.

Have students enter three things they learned in this lesson. With this they can indicate their own learning efficiency of this lesson.

Write down 2 things you want to know more about.

Here, students enter two things they would like to know more about. This not only increases involvement, but also gives them more ownership.

Ask 1 question about something you haven't quite understood yet.

The students indicate here (in question form) with which part of the material they still have difficulty. For the teacher, this not only provides insight into the extent to which the students understand/master the material, but also a good starting point for the next lesson.
