Complete the synthetic division problem below.
enyata [817]

Answer:

D. 2x^2-2x+2

Step-by-step explanation:

Step 1: -3 | 2 4 -4 6

Step 2: -3 | 2 4 -4 6

                    -6  6 -6            

                | 2 -2  2 0

Bring 2 down to the answer then multiply it with 3 and add it with the next coefficient. Repeat the process until you get to the last number and you're done. Sorry its kind of hard to explain the steps for synthetic division. Hope this helps!
