    Need help with second-order ordinary differential equation

    I am finishing up my year of Calc I/II BC. Our teacher is giving us some differential equations work. I don't understand it. Could I get some help with the attached problem.

    Thanks,
    Meks

    Try the substitution y = u y_1 where y_1 satisfies the original ODE and you'll get an ODE for u (missing u, just u' and u'') so letting v = u' you'll get a linear first order ODE which you can solve.

    That should get you started.
