## how would i approach this?

what method do i employ to solve this?

$$y''' + 4y'' + 4y'=0$$

does the above lead to something like this?

$$r^3 +4r^2 +4r=0$$

 Approaching this problem like if it was a 2nd order ODE yield a solution that satisfied the ODE. But I am not sure if this will work all the time.
