I believe that you request about this expression   %28n-4%29%21%2F%283%21%28n-2%29%21%29.


If so,  then

        %28n-4%29%21%2F%283%21%28n-2%29%21%29 = 1%2F%281%2A2%2A3%2A%28n-2%29%2A%28n-3%29%29 = 1%2F%286%2A%28n-2%29%2A%28n-3%29%29.         ANSWER


The rest of the factors in the original expression cancel each other.
