Thanks

4x^2- 7x-1/ [x+1][2x-3] = A+ {B/[x+1]}+{C/[2x-3]}
Now multiply x+1 on the R.h.s which will give u 4x^2-7x-1/[2x-3]
then, substitue x=-1 to get B.
Repeat the same for C, but thn now multiply the R.h.s with [2x-3]
so here x= 3/2
to find A, substitute any num, say for example x= 0 on either sides along with the
values u found for B and C.

....
That gives u A= 2 , B= -2, C=-1

hope it helps.. sorry for the bad drawing..
