Multiplying Binomials: The FOIL Method
The FOIL method is a systematic technique used to multiply two binomials. FOIL stands for First, Outer, Inner, and Last, referring to the position of each term in the binomials being multiplied.
First: Multiply the first terms in each binomial.
Outer: Multiply the outer terms in the product.
Inner: Multiply the inner terms.
Last: Multiply the last terms in each binomial.
Given the expression , apply the FOIL method as follows:
First:
Outer:
Inner:
Last:
Combine all terms:
Simplify by combining like terms:
Example
Multiply using FOIL:
First:
Outer:
Inner:
Last: $6$
Final Answer:
Additional info: The FOIL method is a special case of the distributive property for multiplying any two binomials. This technique is foundational for expanding and simplifying polynomial expressions in algebra.
