FOIL Method(Voice Thread)(CEP 413)Madera SchwaryFall 2011ObjectivesWe will learn how to use the FOIL Method for multiplying polynomials together.

Will go over new vocabulary and review old vocab that relates to this topic.

Students will be able to successfully follow these steps by the end of the lesson.Using the FOIL MethodF FirstO OutsideI InsideL Last

We follow these operations when multiplying Polynomials.(x+3)(x+2)First multiply the first terms (x and x)Outside multiply the terms on the outside (x and 2)Inside multiply the terms on the inside (3 and x)Last multiply the last terms (3 and 2)(x + 3)(x + 2) = x2

(x + 3)(x + 2) = 2x

(x + 3)(x + 2) = 3x

(x + 3)(x + 2) = 6Now we have an equation that looks like this:

x2 + 2x + 3x + 6

We add like terms:

2x + 3x = 5x

And finally we end up with the equation:

x2 + 5x + 6In Conclusion(x + 3)(x + 2) = x2 + 5x + 6
