easy algebraic equation! Messing up somewhere!.:Resolved:.

Hello everyone!
what would this equation be simplified?

Code:

lim x->3   [[1/(x+1)]-1/4]/(x-3);

i keep messing up some place!
forget that it is a limit problem, and can you please show steps so I can see where i'm messing up at?
Thanks for listening!

-1/[4(x+1)]

THanks for the reply but can you see where i made my mistake?
Here is my steps:
find common bottom:
[4/4(x+1) - (x+1)/4(x+1)]/(x-3)
[4-(x+1)/4(x+1)]/(x-3)
[4-x-1/4(x+1)]/(x-3)
[3-x/4(x+1)] (x-3)/1 //was 1/(x-3)
[3x-x^2+3x]/4(x+1)

now i see that is totally wrong, and I don't see which step where i made my mistake.

Code:

 1    1    1
___ - _ * ___
x+1   4   x-3 

     1         1
__________ - _____
(x+1)*(x-3)  4(x-3)

That help?
