    alright so i believe it just wants it simplified. so if you do that you'll get 15x^3-x^2-x+3

    We're just simplifying the problem :) everything that is 12x^3 for example has to be added/subtracted with each other. and so on with each "Like term" in the problem above. So 12x^3 and 3x^3 are added together since they're both positive :)
