A technique for distributing two binomials . The letters FOIL stand for First, Outer, Inner, Last.
First means multiply the terms which occur first in each binomial. Then Outer means multiply
the outermost terms in the product. Inner means multiply the innermost two terms. Last means
multiply the terms which occur last in each binomial. Then simplify the product and combine
any like terrms which may occur.
Example:
(x+3)(x+7)=x.x+x.7+3.x+3.7
FF FO IF IL
First F
O outer
I inner
L last
However it is distributive property only and simplify version.
(x+3)(x+7)=(3+x)(7+x) but positions remain same First ,outer,inner ,last.
So we can not change IFOL or in any permutations.
Example: (x + 2)(x + 5) = x
