Homework Statement


u'''-8u''+2u'-3u=0


Homework Equations





The Attempt at a Solution


So I let:
x1 = u
then x1' = u'
x2 = u'
then x1' = x2
and x2' = u''
x3 = u''
then x2' = x3
and x3' = u'''

I have only done these problems with second order equations, so I don't understand which values I am supposed to plug back into the original equation. Any help is appreciated! Thanks!
