    Please show us how you think these problems should be solved -- or where you're stuck. Do not post any more problems until you've shown us some effort on these other 10 or so problems.

    7(3x^3-1)= 21x^2

    7(2x^2-1)= 14x

    so would it be 21x^2+14x/x

    I don't know how to go further than this

    I don't know the foggiest idea what you are doing.

    first of all, I think you probably meant

    f(x) = (7x^3 + 7x^2)/x , or else the last term would simply be 7x

    from my assumption, then
    f(x) = 7x^2 + 7x
    f'(x) = 14x + 7

    I think i see what i am doing wrong thank you very much :)
