Simplify derivative after using product and chain rule

  1. Jun 4, 2012 #1
    1. The problem statement, all variables and given/known data

    (x[itex]^{2}[/itex]-x[itex]^{-1}[/itex]+1)(x[itex]^{3}[/itex]+2x-6)[itex]^{7}[/itex]

    2. Relevant equations
    Chain Rule & Power Rule


    3. The attempt at a solution

    (x[itex]^{3}[/itex]+2x-6)[itex]^{6}[/itex][(x[itex]^{3}[/itex]+2x-6)(2x+x[itex]^{-2}[/itex])+7(3x[itex]^{2}[/itex]+2)(x[itex]^{2}[/itex]-x[itex]^{-1}[/itex]+1)]

    This is the farthest I've gotten but when I do additional computation I do not arrive at the correct simplified solution.

    edit- should be "simplify derivative after using power rule and chain rule"

    hi biochem850! :wink:

    looks ok so far :smile:

    you've probably made a mistake with a minus somewhere later …

    check them first …

    if that doesn't help, then show us what you did ​
