Homework Statement
Find the solution of the initial value problem.
x'=[3 9; -1 -3]x, x(0)=(2 4)T
Homework Equations
A good guess should be x=tert$ + ert#
The Attempt at a Solution
But ...
the only root is r=0, which gives me a solution x(1)(t)= C1(-3 1)T. Using the guess above, stuff goes wrong because I end up with tA$ + A# -$ = 0, which just gives me #=(-3 1)T as well.
