Jacob is using synthetic division to divide x^3+4x^2−43^x−10 by x−5 Which answer is correct?

x^3+4x^2−43^x−10  by  x−5 

5 [  1      4      -  43      -10 ]

              5         45        10

     ___________________

      1      9          2          0

The remaining polynomial  is   x^2 + 9x + 2
