Homework Help: How would i approach this?

  1. Jun 1, 2005 #1
    what method do i employ to solve this?

    [tex]y''' + 4y'' + 4y'=0[/tex]

    does the above lead to something like this?

    [tex] r^3 +4r^2 +4r=0[/tex]

    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.
