The FOIL method is restrictive to just multiplying two factors that each has two terms. Students still need to learn how to multiply factors that don't have two terms each. Since this last procedure also includes how to multiply two factors each with two terms, then I feel that teachers are showing an extra rule when they show the FOIL method.

Having students learn an extra rule when not needed is not beneficial to the students. They have enough to learn!
