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


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


Using the Table


Using the Table on your own


Extra Examples


Homework

  • Multiplying Binomials: Table Method, Worksheet 1


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
