1 Two Similar Approaches Basic Distributive Property Name:Date:Period:Topic: Multiplying Polynomials Essential Questions: How can you use the distributive property to solve for multiplying polynomials?Two Similar ApproachesBasic Distributive PropertyFOIL
9 2nd Method: FOILThe FOIL method is ONLY used when you multiply 2 binomials. It is an acronym and tells you which terms to multiply. 2) Use the FOIL method to multiply the following binomials: (y + 3)(y + 7).
10 2nd Method: FOIL(y + 3)(y + 7). F tells you to multiply the FIRST terms of each binomial.y2
11 (y + 3)(y + 7). O tells you to multiply the OUTER terms of each binomial.
12 (y + 3)(y + 7). I tells you to multiply the INNER terms of each binomial. y2 + 7y + 3y
13 (y + 3)(y + 7). L tells you to multiply the LAST terms of each binomial. y2 + 7y + 3y + 21Combine like terms.y2 + 10y + 21
14 Remember, FOIL reminds you to multiply the: First termsOuter termsInner termsLast terms
21 Important:By learning to use the distributive property, you will be able to multiply any type of polynomials.We need to remember to distribute eachterm in the first set of parentheses throughthe second set of parentheses.
