    Your answer should be B if you put all the common parts together you will find you can not simplify the equation any longer

    Right... so because there is nothing in common with 2x^6 I leave that then I would add the two common parts together so add 3x^2+3x^2 together and you should get 6x^2

    Then there are no other x's so you leave the x alone. then add the 9&8 together and you should get 17.

    so 2x^3 should be by itself... ha ha it's ok and 2x^2 add that to -3x^2 because they share the same power.. are you following ?

    you should get -x^2... Next, you have the x's with out powers in common (x & -2x) so you should put those together to get -x.
