%284%28h-4%29%29%2F%28h%5E2-16%29


%284%28h-4%29%29%2F%28%28h-4%29%28h%2B4%29%29


%284%2Ahighlight%28%28h-4%29%29%29%2F%28highlight%28%28h-4%29%29%28h%2B4%29%29


%284%2Across%28%28h-4%29%29%29%2F%28cross%28%28h-4%29%29%28h%2B4%29%29


4%2F%28h%2B4%29


So %284h-16%29%2F%28h%5E2-16%29 simplifies to 4%2F%28h%2B4%29


In other words, %284h-16%29%2F%28h%5E2-16%29=4%2F%28h%2B4%29
