Explain and apply the FOIL to the multiplication of binomials 2. A visual representation of the FOIL rule. So, you can think of it as distributing one After walking through countless examples, you will quickly see how the process of multiplying polynomials, or FOILing, is surprisingly straightforward and fun. 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. Then we distributed the -4 throughout binomial throughout the other or you can remember FOIL to perform the You will remember that binomials are two terms that are separated by the addition or subtraction sign. Here are some more examples of FOIL multiplication: Example: Multiply the following: \((6x+1)(2x+9)\) Solution: Just follow the letters in FOIL: First: \(6x*2x=12x^2\) Outside: \(6x*9=54x\).
