What is an example of FOIL method?
Example 1: Multiply the binomials (x + 5)(x − 3) using the FOIL Method. Multiply the pair of terms coming from the first position of each binomial. Multiply the outer terms when the two binomials are written side-by-side. Multiply the inner terms when the two binomials are written side-by-side.
