I wuould please like some verifcation on my work i think am on the write track, the question itself is
For my homogeneous left side equation i have yh(x)=c1e^2x+c2e^-2x
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,
? am not sure if these are my correct coeffcients any help will be appreciated! thanks!
well i dereived my particular solution two times then subbed it into my differential equation when i equated terms i got those numbers but am not sure if my answr is correct i followed all procedures, am using method of undetermined coefficients
I did this..
yp(x)=axe^2x+bx+c i took the dervtive twice then i substtuted it into the de i got
my final equation for the whole DE is...
