Binomials Using Box Method

Front

What is a binomial?

Back

A binomial is a polynomial that contains exactly two terms, such as (a + b) or (x - 3).

Front

What is the box method for multiplying binomials?

Back

The box method involves creating a grid (or box) to organize the multiplication of each term in the first binomial with each term in the second binomial.

Front

Multiply using the box method: (2n + 2)(6n + 1).

Back

12n² + 14n + 2.

Front

Multiply using the box method: (6p + 8)(5p - 3).

Back

30p² - 8p - 64.

Front

Multiply using the box method: (8p - 2)(6p + 2).

Back

48p² + 4p - 4.

Front

Multiply using the box method: (x - 5)(x + 1).

Back

x² - 4x - 5.

Front

Multiply using the box method: (x - 3)(6x - 2).

Back

6x² - 20x + 6.

Front

What is the first step in the box method?

Back

Draw a box divided into four sections for two binomials.

Front

How do you fill in the box in the box method?

Back

Multiply each term of the first binomial by each term of the second binomial and place the results in the corresponding sections of the box.

Front

What do you do after filling in the box?

Back

Add all the terms from the box to get the final polynomial.
