    Your strategy is correct, but

    Look again at your integration line.

    \int {\frac{{dv}}{{{v^3}}}}  + \int {\frac{{dv}}{v}}

    is not what you have.

    You add +1 to the index when you integrate or take the ln if the index is -1

    When you have the correct general solution you should be able to substitute back for v = y/x to obtain the general solution in terms of the original variables.
    Then it is a matter of applying the initial condition y(0)=2
