Bell Ringer Identify the terms like terms constants

Bell Ringer Identify the terms, like terms, constants, and coefficients. #1. #2. #3. #4. 4 m – 5 m + n – 7 6 a – b + 2 a – 7 2 + 6 a + 4 a m + 4 m + 2 m + 5

Oops!!!! Mrs. Key messed up… �Constants are NOT like terms. Like terms are terms that contain the same variable. For example: � 3 x + 6 x + 9 + 2 Constants: � 8 + 4 x + 7 Constants: � 5 y – 4 y + 1 + 4 Constants: � 2 m + 4 n + 3 + 6 Constants: Like Terms:

Vocabulary � Simplest Form: An algebraic expression with no like terms and no parentheses � Simplifying the Expression: Using the Distributive Property to combine like terms � Expression: Any combination of terms and operations � For example: 5 x + 3 � Equation: A mathematical sentence stating that two quantities are equal � For example: 5 x + 3 = 13 � Equivalent Expression: Expressions that have the same value � Distributive Property: To multiply a sum or difference by a number, multiply each term inside the parentheses by the number outside the parentheses

Vocabulary �Term: Parts of an algebraic expression �Coefficient: The numerical part of a term that contains a variable � Like Terms: Terms that contain the same variables �Constant: A term without a variable

Distributive Property Ex 1: 3 ( 2 + 1 ) Ex 3: (-2 + 3 ) (-5) Ex 5: -3 (k – 4) Ex 2: -4 ( 6 – 1 ) Ex 4: Ex 6: 2(m+9) (g – 5) (-1)

Simplifying Expressions Identify the terms, like terms, constants, and coefficients in the following examples. Ex 1: 4 n + 7 w – 6 + 9 – 3 n Ex 2: 7 b – 12 s + 2 – 5 s Simplify the following algebraic expressions. Ex 3: 4 y – 2(x – 3 y) Ex 4: 7 n + 4 – n - 2
