I have a 4th order differential equation with given -2 +3i root.(adsbygoogle = window.adsbygoogle || []).push({});

Now need to find the homogenous solution. Well, if the root was real, it would be easier but now I'm stuck and don't know how to proceed.

What am I supposed to do to solve this ?

Equation is : d^{4}y(t)/dt^{4}+6d^{3}y(t)/dt^{3}+ 22d^{2}y(t)/dt^{2}+ 30dy(t)/dt + 13y(t) = f(t)

Just need to solve the homogenous part so f(t) is just a dummy function
