2z%2F%28z%5E2-16%29+%2B+z%2F%28z-4%29....

=2z%2F%28z%5E2-4%5E2%29+%2B+z%2F%28z-4%29

=2z%2F%28%28z-4%29%28z%2B4%29%29+%2B+z%2F%28z-4%29

=2z%2F%28%28z-4%29%28z%2B4%29%29+%2B+z%28z%2B4%29%2F%28%28z-4%29%28z%2B4%29%29

=%282z+%2B+z%28z%2B4%29%29%2F%28%28z-4%29%28z%2B4%29%29

=%282z+%2Bz%5E2%2B4z%29%2F%28%28z-4%29%28z%2B4%29%29

=%28z%5E2%2B6z%29%2F%28%28z-4%29%28z%2B4%29%29

=z%28z%2B6%29%2F%28%28z-4%29%28z%2B4%29%29
