Lesson Summary:

This lesson teaches students how to multiply two binomials using two different methods, FOIL and the Smiley Face method. FOIL stands for First, Outer, Inner, Last, and the Smiley Face method involves drawing a smiley face and placing the terms in the correct position. Both methods will result in the same answer, as demonstrated in the examples given. These methods only work with two binomials, but the box method can be used for other types of multiplication.

    Learn how to multiply binomials using FOIL and see some examples of how it works. This is also sometimes called the smiley face method. The example (2x - 5)(3x + 4) is used as an example to show the method of FOIL, the smiley face method, and the box method. This is a great intro to multiplying two binomials.
