What to do here if D=d/dx(adsbygoogle = window.adsbygoogle || []).push({});

(D^{2}+2D+4)y= x^{2}e^{2x}?

How to find particular integral by method of undetermined coefficient?

if R.H.S would have been x^{2}+ e^{2x}then we could have taken

y_{p}= Ax^{2}+ Bx+C + De^{2x}

but here in product, what to do?
