Expand the following expressions using the FOIL method. Combine any like terms, but when that is not possible, be sure to follow the order of FOIL: First + Outer + Inner + Last. e.g. Example: Equation: (x + y) (x + y) Answer: x^2 + 2xy + y^2 Show step-by-step Quiz: Equation: (1 + x) (3 + 2x) Show answer | Show step-by-step Equation: (2 + 5x) (11 + 12x) Show answer | Most Algebra books describe FOIL as a method of multiplying two binomials. FOIL is the acronym for First Outside Inside Last Example: Multiply the binomials (x + 1) (2 x – 3) Solution: (x + 1) Use the foil method to solve: (-7 x −3) (−2 x +8) Solution Multiply the first term: = -7x * -2x = 14x 2 Multiply the outer terms: = -7x * 8 = x Multiply the inner terms of the binomial: = – 3 * -2x = How It Works.

FOIL is the acronym for First Outside Inside Last. The following diagram shows how to use the FOIL method to distribute or multiply two binomials. Scroll down the page for more examples and solutions. Multiplying Binomials FOIL Method Multiplying binomials using the FOIL method. Explanation and examples. How to Use Foil to Distribute Two Binomials? This video will show you how to use foil to distribute two binomials. FOIL Method for Multiplying Binomials - Distributive Property In this video, we use the FOIL method to multiple binomials. You multiply first terms, then outside terms, then inside terms, then last terms, and then combine like terms for your answer. The mnemonic F O I L tells us exactly what terms to multiply, and in what order:. By following First, Outer, Inner, Last, we do not overlook any term in either binomial.
All the terms in the first binomial are combined with the terms in the second binomial properly. Everything gets counted. Let's apply the F O I L method on a couple of examples. Let's go through each step of F O I L to solve this multiplication problem:. Now, let's use the F O I L method on this equation:. Multiplying three binomials is a special case for F O I L because the F O I L method can only be used for multiplying two binomials at a time. You can use FOIL to multiply three or more binomials if you pair them off, then factor the answer to the remaining binomial. Then, multiply them using the F O I L method, and we get:. If you are faced with more multiplying two binomials, solve two at a time using F O I L until you are left with just one polynomial. The term polynomial refers to an expression of constants, variables, and exponents that are added, subtracted, or multiplied, like the highlighted answer above.
Each term on its own is called a monomial. Don't foil around with partial work; get answers down on paper before you check our answers. Get better grades with tutoring from top-rated professional tutors. Get help fast. Want to see the tutors near you?
