    You have defined a differential operator:
    [tex]
    T=\frac{d}{dx}-1
    [/tex]
    It is a linear operator, this is clear but it can be proven.

    differential operator thanks, i'm looking forward to that, but before that,

    what should i do to resolve ((d/dx)-1)x^2

    how to do that?

    2x-x^2???

    Correct! Your differential operator says that given a function I should differentiate it and take away the original function.
