Front

What does FOIL stand for in algebra?

Back

FOIL stands for First, Outside, Inside, Last, which are the steps 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

The First step involves multiplying the first terms of each binomial.

Front

What is the Outside step in the FOIL method?

Back

The Outside step involves multiplying the outer terms of the binomials.

Front

What is the Inside step in the FOIL method?

Back

The Inside step involves multiplying the inner terms of the binomials.

Front

What is the Last step in the FOIL method?

Back

The Last step involves multiplying the last terms of each binomial.

Front

Can FOIL be used for more than two binomials?

Back

No, FOIL is specifically designed for multiplying two binomials.

Front

What is the expanded form of (x + 4)(x + 5) using FOIL?

Back

x^2 + 9x + 20.

Front

What is the purpose of the FOIL method?

Back

The purpose of the FOIL method is to simplify the multiplication of two binomials into a polynomial.
