## How to Find Foil Calculator?

The **FOIL** formula helps in remembering the steps required for multiplying two binomials. When the bases are the same, we must remember that we simply add the powers of the base terms.

**FOIL** stands for:

**F:** First ( First term of each binomial are multiplied with each other)

**O:** Outer ( Outer terms are multiplied with each other- e.g., a will be multiplied with d)

**I:** Inner (Inner terms are multiplied with each other - e.g., b will be multiplied with c)

**L:** Last ( Last terms of each binomial are multiplied with each other).

The general form of the FOIL is given by

**General form of the FOIL=** **(a+b) (c+d) = ac + ad + bc + bd**

Let us see an example to understand briefly.

**Solved Example:**

Simplify (2x + 1)(x + 3)

**Solution:**

Given: (2x + 1)(x + 3)

Now using the FOIL formula,

General form of the FOIL= (a+b) (c+d) = ac + ad + bc + bd

(2x + 1)(x + 3) = (2x * x) + (2x * 3) + (1 * x) + (1 * 3)

= 2x^{2} + 6x + x + 3

= 2x^{2} + 7x + 3

Similarly, you can try the calculator to simplify the given expressions:

- (5x - 6)(2x + 7)
- (-7x + 4)((x - 5)
