I have a much simpler method for patial fraction instead of A B,C

In the fraction 3/[n(n+1)(n+2]
HEre subtitute n=0 in in all except n
u will get 3 / n2

now for secnd substitue -1( the zero of n+1) everywhere excpet in the n+1
u will get -3/n+1

now for the third take -2 (the zero of n+ 2)
Put in all except n+2
U will get (3/2) 1/(n+2)

put them together........THIs is very easy......IF U like RATE ME!!!!!!!!!
