Lesson 6.6.7 Equivalent Expressions Thursday, Nov 6 Lesson 6.6.7 Equivalent Expressions
Equivalent Expressions Objective: To understand how to use properties to simplify expressions.
Equivalent Expressions 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.
Equivalent Expressions 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.
Equivalent Expressions A term without a variable is called a constant. e.g. 4x + 4 Constant.
Equivalent Expressions Like terms are terms that contain the same variable. Only like terms can be added or subtracted. e.g. 4x + 6 + 5x Like terms
Equivalent Expressions To simplify an numeric or algebraic expression, use properties to write an equivalent expression that has no like terms and no parentheses. Numeric Algebraic 3 + 3 = 2(3) or 6 x + x = 2x
