Lesson 6.6 The Distributive Property Monday, Jan 11 Lesson 6.6 The Distributive Property

The Distributive Property Objective: To use the Distributive Property to rewrite algebraic expressions.

The Distributive Property Distributive Property (DP) – To multiply a sum by a number, multiply each addend by the number outside the parenthesis. e.g. 4 · (3 + 1) = 4 · 3 + 4 · 1= 12 + 4 = 16 e.g. 4 · (a + 1) = 4 · a + 4 · 1 or 4a + 4 The word distribute means to share.

The Distributive Property A term can be a single number or variable or numbers and variables multiplied together and separated by addition or subtraction. e.g. 4x + 4 This expression has 2 terms.

The Distributive Property A coefficient is the numerical factor of a term that contains a variable. e.g. 4x + 4 In this expression there is only one term that has a variable and the coefficient is 4.

The Distributive Property A term without a variable is called a constant. e.g. 4x + 4 Constant.

The Distributive Property Like terms are terms that contain the same variable. Only like terms can be added or subtracted. e.g. 4x + 6 + 5x Like terms
