You need terms for all degrees for the dividend just as you need to account for all included place values in regular long division. The x=-2 divisor represents the binomial (x+2). 

      -2      |      -3    5      0     -1     7
              |
              |            6     -22    44    -86
              |__________________________________________
                    -3    11     -22    43     -79
