Multiplying Binomials

We learned to multiply a monomial and a polynomial:

Try these two on your own:

Multiplying Binomials

• Now, we will learn how to multiply two binomials together.

• A Binomial is a polynomial with two terms:

Multiplying Binomials

• To multiply two binomials, we multiply each term in the first binomial with each term in the second binomial.

• We can use a table to help keep the multiplication organized.

Using the Table

• Draw a 2 by 2 grid

• Label the rows with the first binomial: one term to the left of each row

• Label the columns with the second binomial: one term above each column

• Multiply across the rows and columns to fill in the table

• Write the result as the product of the binomials

• Combine like terms

Homework

Variations on multiplying

• There may be other variables

• There may be higher powers

• There may be no like terms to combine

• You will need to put the answer in standard form
