+%28m%2Bn%29%5E%28-1%29%2F%28m%5E%28-2%29-n%5E%28-2%29%29+

lets look at the denominator first:
+m%5E%28-2%29-n%5E%28-2%29+
+1%2Fm%5E2-1%2Fn%5E2+
+%28n%5E2%2F%28n%5E2m%5E2%29%29-%28m%5E2%2F%28m%5E2n%5E2%29%29+
+%28%28n%5E2-m%5E2%29%2F%28n%5E2m%5E2%29%29+

so we end up with:
+%28m%2Bn%29%5E%28-1%29%2F%28%28n%5E2-m%5E2%29%2F%28n%5E2m%5E2%29%29+
+%28m%2Bn%29%5E%28-1%29%2A%28%28n%5E2m%5E2%29%2F%28n%5E2-m%5E2%29%29+
+%281%2F%28m%2Bn%29%29%2A%28%28n%5E2m%5E2%29%2F%28n%5E2-m%5E2%29%29+
+%281%2F%28m%2Bn%29%29%2A%28%28n%5E2m%5E2%29%2F%28%28n-m%29%28n%2Bm%29%29%29+
+%281%2F%28n%2Bm%29%29%2A%28%28n%5E2m%5E2%29%2F%28%28n-m%29%28n%2Bm%29%29%29+
+%28n%5E2m%5E2%29%2F%28%28n-m%29%28n%2Bm%29%28n%2Bm%29%29+
+%28n%5E2m%5E2%29%2F%28%28n-m%29%28n%2Bm%29%5E2%29+
