    Answer:

    a=0

    Step-by-step explanation:

    According to problem

     {m}^{3}  + 2m + a = 12 \\  {2}^{3}  + 2 \times 2 + a = 12 \\ 8 + 4 + a = 12 \\ a = 12 - 8 - 4 \\ a = 0

    Hope it helps you.

    Step-by-step explanation:

    m3+2m+a=12

    m=2.

    (2)3+2(2)+a=12

    8+4+a=12

    12+a=12

    a=12-12

    a=0
