Please help me simplify this complex rational expression 1-(4/x+2)÷1-(1/x-1)=

placement of parentheses can make a huge difference, for example you wrote this: 
1-(4/x+2)÷1-(1/x-1) 
which converts to 
1-%284%2Fx%2B2%29%2F1-%281%2Fx-1%29 
but I think you meant to write: 
(1-4/(x+2))/(1-1/(x-1)) 
which converts to 
%281-4%2F%28x%2B2%29%29%2F%281-1%2F%28x-1%29%29
simplifying...
