“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.
Did Cherise use algebra tiles to correctly represent the product of (x – 2)(x – 3)? No, she did not multiply the negative integer tiles by the other negative integer tiles correctly. … There are 3 terms in the product.
Outside terms are multiplied next: q * (−7) = −7q. Inside terms are multiplied next: −3 * q = −3q. Last, multiply last terms of each binomial: −3 * (−7) = 21.
UnFOILing is a method for factoring a trinomial into two binomials. When you multiply two binomials together, you use the FOIL method, multiplying the First, then the Outer, then the Inner, and finally the Last terms of the two binomials into a trinomial.
Factorising is the reverse of expanding brackets, so it is, for example, putting 2x² + x – 3 into the form (2x + 3)(x – 1). This is an important way of solving quadratic equations. The first step of factorising an expression is to ‘take out’ any common factors which the terms have.

That is, foil tells you to multiply the first terms in each of the parentheses, then multiply the two terms that are on the “outside” (furthest from each other), then the two terms that are on the “inside” (closest to each other), and then the last terms in each of the parentheses.
