Solve this equation by superposition approach (undetermined coefficients); pg. 154 in Zill, according to the formula Y = Yc + Yp(adsbygoogle = window.adsbygoogle || []).push({});

----------------------------------------------------

y''' -2y'' -4y' +8y = 6xe^(2x)

I got:

Yc = C1 e^(-2x) + C2 e^(2x) + C3 xe^(2x)

for the complementary function Yc...

I'm having trouble finding the particular solutions Yp

Any help is greatly appreciated
