Is FOIL method a special products?
The FOIL method is a special case of a more general method for multiplying algebraic expressions using the distributive law. The word FOIL was originally intended solely as a mnemonic for high-school students learning algebra.
Why is the FOIL method called special?
A shortcut called FOIL is sometimes used to find the product of two binomials. It is called FOIL because we multiply the first terms, the outer terms, the inner terms, and then the last terms of each binomial. The FOIL method arises out of the distributive property.
What is the example of FOIL method?
FOIL math examples 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.
What is foil method in math?
The FOIL method lets you multiply two binomials in a particular order. The letters in FOIL refer to two terms (one from each of two binomials) multiplied together in a certain order: First, Outer, Inner, and Last.
What is the meaning of special products?
Special products are simply special cases of multiplying certain types of binomials together. We have three special products: (a + b)(a + b)
How do you answer the FOIL method?
The FOIL method lets you multiply two binomials in a particular order….See how the FOIL numbered steps work on a couple of negative terms.
- Multiply the first terms.
- Multiply the outer terms.
- Multiply the inner terms.
- Multiply the last terms.

How do you FOIL numbers?
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.
Why is it called special products?
Binomials and FOIL In this lesson, we are going to concentrate on multiplying binomials. We do so by multiplying the first terms of each binomial together to get xr. These special cases are called special products because they are special cases of products of binomials.
What does the FOIL rule mean in math?
A visual representation of the FOIL rule. Each colored line represents two terms that must be multiplied. In elementary algebra, FOIL is a mnemonic for the standard method of multiplying two binomials —hence the method may be referred to as the FOIL method.
What is the use of FOIL method?
FOIL method The FOIL Method is used to multiply binomials. F OI L F O I L is an acronym. The letters stand for First, Outside, Inside, and Last, referring to the order of multiplying terms.
Can the FOIL rule be used to expand a product?
The FOIL rule cannot be directly applied to expanding products with more than two multiplicands or multiplicands with more than two summands. However, applying the associative law and recursive foiling allows one to expand such products. For instance,
What does the letters foil stand for?
The letters FOIL stand for First, Outer, Inner, Last. First means multiply the termswhich occur first in each binomial. Then Outer means multiply the outermost terms in the product. Inner means multiply the innermost two terms.
