Essential Questions How do we use long division and synthetic division to divide polynomials?

Polynomial long division is a method for dividing a polynomial by another polynomials of a lower degree. It is very similar to dividing numbers.

Example 1: Using Long Division to Divide a Polynomial 1. What do you multiply x by to get 2x2 2. Multiply by dist. prop 3. Change signs and add 4. What do you multiply x by to get –13x 5. Multiply by dist. prop 6. Change signs and add

Example 2: Using Long Division to Divide a Polynomial 1. What do you multiply x by to get x2 2. Multiply by dist. prop 3. Change signs and add 4. What do you multiply x by to get -4x 5. Multiply by dist. prop 6. Change signs and add

Example 3: Using Long Division to Divide a Polynomial 1. What do you multiply x by to get 2x3 2. Multiply by dist. prop 3. Change signs and add 4. What do you multiply x by to get 6x2 5. Multiply by dist. prop 6. Change signs and add 7. What do you multiply x by to get 13x 5. Multiply by dist. prop 6. Change signs and add
