To watch a video to multiply binomials together, go to the Internet and type the keywords “Math Dude” into a search engine. These keywords should take you to the Montgomery County Public Schools website. On the right side of the website, look for the heading “Algebra 1 Unit 6.” Then choose the video titled “Multiplying Polynomials.”

 

Go back to the Are You Ready? section, and try the questions again. If you are still having difficulty, contact your teacher.
