Answer:

a= -14  half of a = -7

Step-by-step explanation:

                             6x +(a+12)

       x-2                 6x2 +ax + 7

                             6x2-12x

                                -----------

                                    (a+12)x+7

                                    (a+12)x-2(a+12)

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

                                               7+2(a+12)

Given remainder is 3

7+2(a+12) = 3

 7+2a +24 =3

   2a +31  = 3

      2a   = 3-31

        2a = -28      

          a = -14

Half of a = -7
