1. Lesson 3-2 Pages 103-107 Simplifying Algebraic Expressions Lesson Check 3-1

2. What you will learn! How to use the Distributive Property to simplify algebraic expressions.

3. Equivalent Expressions Terms Like Terms CoefficientConstant Simplest Form

4. What you really need to know! Equivalent Expressions: Expressions that have the same value.

5. What you really need to know! Term: a number, a variable, or a product of numbers and variables. Coefficient: the numerical part of a term that also contains a variable.

6. What you really need to know! Constant: term without a variable. Like terms: terms that contain the same variables.

7. What you really need to know! When an algebraic expression has no like terms and no parentheses, we say that it is in simplest form.

9. Example 1: Identify the terms, like terms, coefficients, and constants in the expression. 4x - x + 2y - 3 Terms: 4x, -x, 2y, -3 Coefficients: 4, -1, 2 Like terms: 4x, -x Constant: -3

10. Example 2: Simplify each expression: 5x + 4x 9x

11. Example 3: Simplify each expression: 8n + 4 + 4n 12n + 4

12. Example 4: Simplify each expression: 6x + 4 - 5x - 7 x - 3

13. Example 5: Simplify each expression: -y + 2(x + 3y) 2x + 5y -y + 2x + 6y

14. Example 6: You and a friend worked in the school store last week. You worked 4 more hours than your friend. Write an expression in simplest form that represents the total number of hours you both worked. Define the hours as h. h + (h + 4) = 2h + 4
