Question 1129168


{{{(3/(x+1) - 2/(x-1) )/(1/(x+2) + 2/(x-1) )}}}


{{{((3(x-1)  - 2(x+1))/((x+1)(x-1)) )/(((x-1)  + 2(x+2))/((x-1)(x+2)) )}}}


{{{((3x-3  - 2x-2)/((x+1)cross((x-1))) )/((x-1)  + 2x+4)/(cross((x-1))(x+2)) )}}}


{{{((x-5)/(x+1) )/((3x+3)/(x+2) )}}}


{{{((x-5)(x+2) )/(3(x+1)(x+1))}}}


{{{((x-5)(x+2) )/(3(x+1)^2)}}}
