Answer 2

Answer:

b^2 - 3b + 18  R 2.

Step-by-step explanation:

Using long division:

           b^2 - 3b + 18    <----------------Quotient.

          ----------------------------------

b + 7 ) b^3 + 4 b^2 - 3b + 128

          b^3 + 7b^2

                  -3 b^2 - 3b

                  -3 b^2 -21b

                              18b + 128

                              18b +  126

                                            2  <--------- remainder.
