FOIL - First Outside Inside Last - A method for multiplying two binomials
98^2 no calculator FOIL
98 = 100 - 2
(100 - 2)(100 - 2)
Using FOIL:
100^2 - 100(2) - 100(2) + -2^2
10000 - 400 + 4

Binomial Multiplication (FOIL)
Free Binomial Multiplication (FOIL) Calculator - Multiplies out the product of 2 binomials in the form (a + b)(c + d) with 1 unknown variable.
This utilizes the First-Outside-Inside-Last (F.O.I.L.) method.
Expand Master and Build Polynomial EquationsFree Expand Master and Build Polynomial Equations Calculator - This calculator is the ultimate expansion tool to multiply polynomials. It expands algebraic expressions listed below using all 26 variables (a-z) as well as negative powers to handle polynomial multiplication. Includes multiple variable expressions as well as outside multipliers.
Also produces a polynomial equation from a given set of roots (polynomial zeros). * Binomial Expansions c(a + b)x
* Polynomial Expansions c(d + e + f)x
* FOIL Expansions (a + b)(c + d)
* Multiple Parentheses Multiplications c(a + b)(d + e)(f + g)(h + i)
Which of the following is equivalent to 3(2x + 1)(4x + 1)?
Which of the following is equivalent to 3(2x + 1)(4x + 1)?

[*]A) 45x
[*]B) 24x^2 + 3
[*]C) 24x^2 + 18x + 3
[*]D) 18x^2 + 6

First, [URL=' the binomials[/URL]:
We get 8x^2 + 6x + 1
Now multiply this polynomial by 3:
3(8x^2 + 6x + 1) = [B]24x^2 + 18x + 3, answer C[/B]
