After cross multiply we have in num: ((x+2) * (x+1)) + ((x-2) * (x-1)) ---> Solving the equation we get 2(x^2 +2)
Denominator will be x^2 - 1
Hence final solution will be 2(x^2+2) / x^2 - 1 and option E

A better approach is to plugin the value , lets say value of x = 0 and substitute in the question. it gives the value of -4.
The same to check with the options and leaves the option E for the equation.
