Unit 2: Algebra Lesson 3: The Distributive Property Learning Goal: I can simplify algebraic expressions using distributive property
Unit 2: Algebra Lesson 3: The Distributive Property We can multiply or divide a polynomial by a constant. To simplify this, the polynomial must be expanded using the distributive property.
STEPS: 1.Multiply/divide each term in the polynomial by the constant 2.Keep the variables the same 3.Simplify signs 4.Identify like terms 5.Combine like terms Unit 2: Algebra Lesson 3: The Distributive Property
