What ordinary differential equation? Simple answer is needed

    What ordinary differential equation? Simple answer is needed!!!

    1. The problem statement, all variables and given/known data
    instead [delta] i will use 'd'.
    in these two example, what kind of ordinary dif. eq. are implied by the methodd of seperation of variables.
    first one is;

    du/dt=(d^2u)/(dx^2) - 5 du/dt

    and other one is;

    du/dt=2(d^4u/dx^4)

    'd' is [delta] in these examples...
    Thanks for now..

    2. Relevant equations



    3. The attempt at a solution

    Well, what have you done? Since the problems refers to what you would get "by the methodd of separation of variables", what is the "method of separation of variables?
