FOIL Method

Front

What does FOIL stand for in the FOIL method?

Back

FOIL stands for First, Outside, Inside, Last, which are the terms used to remember the order of multiplying two binomials.

Front

What is the result of (a + b)(c + d) using the FOIL method?

Back

The result is ac + ad + bc + bd.

Front

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

Back

First: 3x * 3x = 9x²; Outside: 3x * 2 = 6x; Inside: 2 * 3x = 6x; Last: 2 * 2 = 4. Combine: 9x² + 12x + 4.

Front

What is the expanded form of (x + 7)(x + 9) using the FOIL method?

Back

x² + 16x + 63.

Front

What is the result of (x - 1)(x - 8) using the FOIL method?

Back

x² - 9x + 8.

Front

What is the result of (x - 7)(x + 7) using the FOIL method?

Back

x² - 49.

Front

How do you apply the FOIL method to (4x + 3)(x + 2)?

Back

First: 4x * x = 4x²; Outside: 4x * 2 = 8x; Inside: 3 * x = 3x; Last: 3 * 2 = 6. Combine: 4x² + 11x + 6.

Front

What is the purpose of the FOIL method?

Back

The FOIL method is used to multiply two binomials quickly and efficiently.

Front

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

Back

No, the FOIL method is specifically designed for multiplying two binomials (two-term polynomials).

Front

What is the first step in the FOIL method?

Back

Multiply the First terms of each binomial.
