 This Lesson (FOIL Method for Middle Schoolers) was created by by Spearmint(0)  : View Source, ShowAbout Spearmint: Any Small Levels of Math for Elementary and Middle School Users Lets start out with a simpler problem...FOIL only works for binomials. (3x^2+5)(2x^2-6) F= Is For First Terms of Each Problem, in this case, F-6x^4, because you multiply 3x times 2x and get 6x. You then add the exponents in a multiplication problem, such as exponentials 2+2. You then get 6x^4 O= Is for the outer termsof each binomial. In this case, O- -18x^2, doing as if what you did in F. I= Is for the inner terms in each binomial. In this case, I- 10x^2...getting it? L= Is for the last terms of each binmoial. In this case, L- -30. put all the terms together, 6x^4-18x^2+10x^2-30 add all like terms, in this case, the like terms are -18x^2 and 10x^2. The equal terms are -8x^2. now put the terms together, and you have: 6x^4-8x^2-30. now you have your answer, it is 6x^4-8x^2-30. GOOD JOB IF YOU UNDERSTOOD IT!! if not, i can post another example later. such as: (9t+12)(12t-18) F= equals....first terms...first terms are 9t and 12t equaling 108t^2 when multiplying. O= equals....outer terms....outer terms are 9t and -18 equaling to -162t. I= equals....inner terms....inner terms are 12 and 12t equaling to 144t. L= equals....last terms.....last terms are 12 and -18 equaling to -216. 108t^2-162t+144t-216. add like terms, like terms are -162t and 144t. those equal up to -18 t. end of the problem is 108t^2-18t-216. more examples, will post later.
