first one is correct
3%2F%28x-y%29+-+%282y+%2B+x%29%2F%28x%5E2-y%5E2%29+=+%282x%2By%29+%2F+%28x%5E2-y%5E2%29-> true

second one should be:

%283x%2B4%29%2F%28x%5E2-4%29+%2B+%284x-5%29%2F%28x%2B2%29

= %283x%2B4%29%2F%28x%5E2-2%5E2%29+%2B+%284x-5%29%2F%28x%2B2%29

= %283x%2B4%29%2F%28%28x-2%29%28x%2B2%29%29+%2B+%284x-5%29%2F%28x%2B2%29

=

=+%283x%2B4%2B%284x-5%29%28x-2%29%29%2F%28%28x-2%29%28x%2B2%29%29

= %283x%2B4%2B4+x%5E2+-+13x+%2B+10%29%2F%28%28x-2%29%28x%2B2%29%29

= %284x%5E2+-+10x+%2B+14%29%2F%28%28x-2%29%28x%2B2%29%29

= %282%282x%5E2+-+5x+%2B+7%29%29%2F%28%28x-2%29%28x%2B2%29%29
