ByAnalyzing Patterns when Multiplying Polynomials. Carol A. Marinas, Ph.D. Using the Distributive Property. When multiplying terms together, use the distributive property and then simplify. Example: (x + 4) ( x + 3) = x (x + 3) + 4 (x + 3)

BySolve Multi-step Equations. 4x + 7 ( x – 2 ) = -8. 3 ( x – 4 ) = 6. Students will solve equations with multiple steps (more than two) using distributive property, combining like terms, and inverse operations. -3 = 3a + 5 ( a – 9 ) + 4. POWER to the brain. m – 9 – ( 3m + 4 ) = 1.

By2-3 Solving Multi-Step Equations. To solve multi-step equations you use the properties of equality, inverse operations, and properties of real numbers. You will use these properties until the variable is isolated. Problem 1: Combining Like Terms.
