  5. 5. Warm-Up:(4) 1. Simplify: 9( a2 + 2ab - b2) - 2(a2 + ab) 2. 3. 3x + 1 + 5 4x 2x What is the common denominator? x3 + 2x2 - x We are not dividing monomials, so the rules are a x bit different. ....Which brings us to today's class notes 4. Divide:
  6. 6. Polynomial Division Part I: Dividing Monomial by Monomial: Part II: Dividing by a Monomial: A. Take each term in the numerator and divide by the denominator. The result is now a monomial divided by a monomial for each term. Solve as usual. 18x4 -10x2 + 6x7 2x2
