# FOIL Calculator

## Apply FOIL step by step

The calculator will multiply two binomials using the FOIL method, with steps shown.

Effortlessly multiply binomials with our robust FOIL Calculator. This online resource helps expand expressions, saving valuable time and reducing manual calculations.

## How to Use the Foil Calculator?

### Input

Input the polynomial expression you wish to multiply using the FOIL method. Make sure the expression is the product of two binomials.

### Calculation

After you've entered your expression, click the "Calculate" button. The calculator will promptly apply the FOIL method on the entered expression.

### Result

The calculator will show the computed result of the multiplication. Using the FOIL technique, which signifies first, outer, inner, and last, it multiplies the respective terms together and adds up the resulting terms to deliver the final expression.

## What Is the FOIL Method?

The FOIL Method is an important technique used in algebra to ease the multiplication process of two binomials. The term "FOIL" is an acronym that denotes "first, outer, inner, last," outlining the sequence in which the terms should be multiplied.

Let's illustrate this with an example.

Consider the multiplication of two binomials, $$$a + b$$$ and $$$c + d$$$. The FOIL method can be applied as follows:

**First:**Multiply the first terms in each binomial, $$$ac$$$.**Outer:**Multiply the outermost terms in the expression, $$$ad$$$.**Inner:**Multiply the innermost terms, $$$bc$$$.**Last:**Finally, multiply the last terms in each binomial, $$$bd$$$.

The final answer is the sum of the resulting terms: $$$ac+ad+bc+bd$$$.

## Is FOIL the same as reverse FOIL?

The terms FOIL and reverse FOIL are related but refer to two different processes in algebra.

Reverse FOIL is a method to factor quadratic expressions back into two binomials. Consider the quadratic expression $$$x^2+2x-3$$$. We want to find two binomials that will give us this expression when multiplied using the FOIL method.

We look for two numbers that add up to the coefficient of the $$$x$$$ term ($$$2$$$ in this case) and, when multiplied, give the constant term ($$$-3$$$ in this case). The numbers $$$3$$$ and $$$-1$$$ satisfy these conditions.

So the quadratic expression $$$x^2+2x-3$$$ can be factored into $$$(x+3)(x-1)$$$ using reverse FOIL. You can verify this by applying the FOIL method to $$$(x+3)(x-1)$$$; the result will be the original expression $$$x^2+2x-3$$$.
