How to multiply binomials using FOIL

Triangle Suitcase: Rebecca Zook's Blog About Learning

Here’s how to multiply binomials using FOIL (first, outer, inner, last).

I split the video into ten brief parts. Each part features one practice problem, fully explained and demonstrated on the whiteboard.

Click on “more” for the other parts of the video — four more examples, extra practice problems for you to test your mastery of FOIL, and answers to the extra practice problems!

If you, your family, or your friends would like to see me make an instructional video about a particular math topic or type of problem, let me know by leaving me a comment.

And if you like the video, please feel free to click on the “heart” to show that you “heart” it. <3
