Homework Statement
(D^2 + 2D + 10)^2 * (D^2 - 2D -3)y = 0.
Homework Equations
D = d/dx
The Attempt at a Solution
Solving for the roots gives:
-1 + 3i, -1 - 3i <== both of multiplicity 2
and 3, -1.
So the general solution should be:
y = Ae^(3x) + Be^(-x) + Ce^(-x)cos(3x) + Dxe^(-x)cos(3x) + Ee^(-x)sin(3x) + Fxe^(-x)sin(3x)
Am I handling this correctly?
Thanks
