Always eliminate the first one before moving on. Remember to drop down monomials, like you would a normal division problem.

                     2x² + 10x + 18
         __________________
x + 3 | 2x³ + 16x² - 12x + 9
         -(2x³ + 6x²)
         -------------------------------
                    10x² - 12x
                  -(10x² - 30x)
         -----------------------------
                            + 18x + 9
                          - (18x + 54)
                    ----------------------
                                      -45


  2x² + 10x + 18        R: -45/x + 3 is your answer R: = remainder


hope this helps
