The document describes the FOIL method for multiplying two binomial expressions. FOIL is an acronym that stands for First, Outside, Inside, Last, referring to the order of multiplying the terms - first terms, outside terms, inside terms, and last terms. As an example, it shows multiplying (2x+3)(5x-1) using FOIL, obtaining the result of 10x^2 + 13x - 3.

2. Multiplication of:
• F: First terms
• O: Outside terms
• I: Inside Terms
• L: Last terms
• Example Expression:
(2x+3)(5x-1)
FOIL
METHOD

3. • Using our example
expression (2x+3)(5x-1)
we can determine our
answer.
• F: 2x times 5x = 10x^2
• O: 2x times -1 = -2x
• I: 3 times 5x = 15x
• L: 3 times -1 = -3
EXAMPLE

4. • Now we add the
resulting terms.
• 10x^2-2x+15x-3=
•10x^2+13x-3
