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.
a (b + c) AND
= ab + ac =
STEPS:1. Multiply/divide each term in the polynomial
by the constant2. Keep the variables the same3. Simplify signs4. Identify like terms5. Combine like terms
