@Annie96 Can you check the instructions for the question to see if you are expected to give one choice or many?

Maybe they are looking for the one that isn't in standard form?

  • jchick
But they are all in standard form which doesn't make sense because they are looking for one.

@annie96 This is how you should have worked it out: 12x^3+5+5x^2-6x^2-3x^3-9-x =(12x^3-3x^3) +(5x^2-6x^2) -x +(5-9) = ?
