Multiply the 2 binomials using FOIL:
(w + 8)(w - 4)
Define FOIL Formula:
First-Outside-Inside-Last:
(a + b)(c + d) = (a * c) + (b * c) + (a * d) + (b * d)
Set our FOIL values:
a = w, b = 8, c = w, and d = -4
Evaluate:
(w + 8)(w - 4) = (w * w) + (8 * w) + (w * -4) + (8 * -4)
(w + 8)(w - 4) = w2 + 8w - 4w - 32
w2 + 4w - 32
You have 1 free calculations remaining
What is the Answer?
w2 + 4w - 32
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.
This calculator has 2 inputs.
What 2 formulas are used for the Binomial Multiplication (FOIL) Calculator?
FOIL = First, Outside, Inside, Last. Multiply the first terms together, then the outside terms together, then the inside terms together, then the last term together.
(a + b)(c + d) = ab + ad + bc + bd
(a + b)(c + d) = ab + ad + bc + bd
