-12*y' + 4*y'' + y''' = 4*exp(2*x)*sin(2*x)

                -6*x   /     5*sin(2*x)   3*cos(2*x)\  2*x
y(x) = C1 + C3*e     + |C2 - ---------- - ----------|*e   
                       \         68           68    /     
$$y{\left(x \right)} = C_{1} + C_{3} e^{- 6 x} + \left(C_{2} - \frac{5 \sin{\left(2 x \right)}}{68} - \frac{3 \cos{\left(2 x \right)}}{68}\right) e^{2 x}$$
