Answer:

P(x) = (3x^2 + -4x + 6)(x +1 ) + ( 1 )/( x + 1)

Step-by-step explanation:

First we have to divide the polynomial

3x^3  - x^2 + 2x + 7    |  x+1  

-3x^3 - 3x^2                3x^2 - 4x +6

         -4x^2 +2x +7

          4x^2 +4x    

                    6x + 7

                    -6x - 6

                            1

Hence we have

P(x)=(x-k)Q(x) + R(x) = (x-k)Q(x) + 1/(x-k)

P(x) = 3x^3 - x^2 + 7 = (3x^2 + -4x + 6)(x +1 ) + ( 1 )/( x + 1)

HOPE THIS HELPS!!
