**Problem Statement:**

Find the homogeneous equation with constant coefficients that has the given general solution:

\[ y = C_1 e^{-2x} + C_2 x e^{-2x} + C_3 \cos(2x) + C_4 \sin(2x) \]

**Options:**

a) \( y^{(4)} + 8 \, y''' + 4 \, y'' + 16 \, y' + 16y = 0 \)

b) \( y^{(4)} + 2 \, y''' - 2 \, y' + y = 0 \)

c) \( y^{(4)} + 8 \, y''' + 4 \, y'' + 16 \, y' + 16y = 0 \)

d) \( y^{(4)} + 8 \, y''' - 4 \, y'' - 16 \, y' + 16y = 0 \)

e) \( y^{(4)} - 4 \, y''' + 16 \, y' - 16y = 0 \)

f) None of the above. 

(Note: Options a and c are identical.)
