My particular guess for the right side was: ae^2x + bx + c (and since e^2x appears both in the homo and the right side i multiply by x so i have )
axe^2x+bx+c as my guess doing the deritive and equating like terms i get,
a=4/3, b=-3,c=1/4
? am not sure if these are my correct coeffcients any help will be appreciated! thanks!
