when do you use the foil method in algebra
FOIL method In elementary algebra, FOIL is a mnemonic for the standard method of multiplying two binomials[1]â€”hence the method may be referred to as the FOIL method. The word FOIL is an acronym for the four terms of the product:
Product (mathematics) In mathematics, a product is the result of multiplying, or an expression that identifies factors to be multiplied. Thus, for instance, 6 is the product of 2 and 3 (the result of multiplication), and   x ⋅ ( 2 + x )  {\displaystyle x\cdot (2+x)}  is the product of   x  {\displaystyle x}  and   ( 2 + x )  {\displaystyle (2+x)}  (indicating that the two factors should be multiplied together).
