Multiply the 2 binomials using FOIL:
(4x - 5)(x - 3)
Define FOIL Formula:
First-Outside-Inside-Last:
(a + b)(c + d) = (a * c) + (b * c) + (a * d) + (b * d)
Set our FOIL values:
a = 4x, b = -5, c = x, and d = -3
Evaluate:
(4x - 5)(x - 3) = (4x * x) + (-5 * x) + (4x * -3) + (-5 * -3)
(4x - 5)(x - 3) = 4x2 - 5x - 12x + 15
4x2 - 17x + 15
What is the Answer?
4x2 - 17x + 15
How does the Binomial Multiplication (FOIL) Calculator work?
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.
