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)
= 2x2 + 6x + x + 3
= 2x2 + 7x + 3
Similarly, you can try the calculator to simplify the given expressions:
- (5x - 6)(2x + 7)
- (-7x + 4)((x - 5)
