    Some simplification help please

    I want to simplify:

    (3x^2 +2) (x^2 +3) - (x^3 +2x+1)2x

    According to my textbook, I should be arriving at:


    x^4 + 7x^2 - 2x + 6

    I'm getting a little stuck here! help would be kindly appreciated.

    Expand everything:

    (3x^4 + 9x^2 + 2x^2 + 6) - (2x^4 + 4x^2 + 2x)

    = (3x^4 + 11x^2 + 6) - (2x^4 + 4x^2 + 2x)

    = x^4 + 7x^2 - 2x + 6
    Thanks from euphmorning
