Answer:

The answer to your question is: letter A

Step-by-step explanation:

          7 - 2z - 4(z³ - (z³ +4z² + 11z +14)/z + 2)

The result of the division was x² -2x + 7, then

          7 - 2z - 4(z³ - z² + 2z - 7)

          7 - 2z - 4z³ + 4z² - 8z + 28

         -4z³ + 4z² - 10z + 35

             Synthetic division

                                          1    4    11   14      -2

                                             -2   -4   -14

                                          1    2   7     0

               then = z² - 2z + 7
