Multiplying binomials This is called the Box method

Multiplying binomials A binomial has two terms. We will be multiplying pairs of numbers.

Example 1 Multiplying binomials – 3 x²

Example 1 Multiplying binomials – 3 x² -5x

Example 1 Multiplying binomials – 3 x² -5x -3x

Example 1 Multiplying binomials – 3 x² -5x -3x + 15

Example 1 Multiplying binomials x² - 5x – 3x + 15 x² -5x -3x + 15 Write in standard form.

Example 1 Multiplying binomials x² - 5x – 3x + 15 x² - 8x + 15 Combine Like Terms

Multiplying binomials x² - 8x + 15 Final Answer

Example 2 Multiplying binomials + 2 x²

Example 2 Multiplying binomials + 2 x² + 4x

Example 2 Multiplying binomials + 2 x² + 4x + 2x

Example 2 Multiplying binomials + 2 x² + 4x + 2x + 8

Example 2 Multiplying binomials x² + 4x + 2x + 8 x² + 4x + 2x + 8 Write in standard form.

Example 2 Multiplying binomials x² + 4x + 2x + 8 x² + 6x + 8 Combine Like Terms

Multiplying binomials x² + 6x + 8 Final Answer

Multiplying binomials Your final answer should always have an x² first and a whole number at the end. This is called standard form.
