FOIL

Front

What does FOIL stand for in algebra?

Back

FOIL stands for First, Outside, Inside, Last. It is a method used to multiply two binomials.

Front

How do you apply the FOIL method to (x + 2)(x + 3)?

Back

First: x*x = x^2; Outside: x*3 = 3x; Inside: 2*x = 2x; Last: 2*3 = 6. Combine: x^2 + 5x + 6.

Front

What is the result of applying FOIL to (a + b)(c + d)?

Back

The result is ac + ad + bc + bd.

Front

What is the First step in the FOIL method?

Back

Multiply the first terms of each binomial.

Front

What is the Outside step in the FOIL method?

Back

Multiply the outer terms of the binomials.

Front

What is the Inside step in the FOIL method?

Back

Multiply the inner terms of the binomials.

Front

What is the Last step in the FOIL method?

Back

Multiply the last terms of each binomial.

Front

Can FOIL be used for polynomials with more than two terms?

Back

No, FOIL is specifically for multiplying two binomials. For polynomials with more than two terms, use distribution.

Front

What is the expanded form of (x + 5)(x + 2) using FOIL?

Back

x^2 + 7x + 10.

Front

What is the purpose of the FOIL method?

Back

To simplify the multiplication of two binomials into a polynomial.
