Foil Math Online Tutoring - Foil Math Online Tutors The method which is used to multiply two binomials is known as the Foil Math. F stands for first which means that multiply the first variable in each binomial. O stands for outside which means that we have to multiply outside variable. I stands for inside which means multiply the inside variables. L stands for last which means that multiply last variable in each binomial. The parentheses are used for the multiplication sign. Example :Let us find the multiplication of the following binomials (a + x) (a-x) Solution :Applying FOIL method we get the following solution step by step. F stands for first which means that multiply the first variable in each binomial. a.a O stands for outside which means that we have to multiply outside variable. -x.x I stands for inside which means multiply the inside variables. x.a L stands for last which means that multiply last variable in each binomial -x.a Combing the result of the FOIL a.a x.x + x.a - x.a = a x Example :Let us find the multiplication of the following binomials (a - x) (a + ax +x) Solution :Applying FOIL method we get the following solution step by step. F stands for first which means that multiply the first variable in each binomial. a.a O stands for outside which means that we have to multiply outside variable. x.a + ax I stands for inside which means multiply the inside variables. -xa L stands for last which means that multiply last variable in each binomial -a x - x. x Combing the result of the FOIL a.a + x.a + ax -xa -a x - x. x = a - x
