So what kind of complimentary solution did you get? Was there any overlap? :)

D=-1 , 2
Yp=Ax+B+Cxe-x
find A B C

Woops I should have called the exponential term C, sorry about that.

but you mentioned Yp1 and its ok.

so Yp2=Cxe-x

Yp2 is the same as in the auxillary eqtn

no it has x
so xe-x

yes, multiplied it with x, and then?

what will be the value of C?

Tricky it is -2

how is that so? i keep on getting 3/2

I found it with Laplace !

teach me master. what is laplace?

no it is 6/(-1-2)=-2

Don't pay attention that just put in DE and find out A B C especially C. C=-2

i get it. jeeeeeez, stupid mistake.

thanks a lot!

for A B
0-A-2(Ax+B)=6x
A=-3 B=3/2
