+4y+-+3%2F%286y%29+
You can reduce the fraction by dividing out the 3 factor:
%284y%29%2F1+-+1%2F%282y%29+

Next find a common denominator, which is 2y. You must multiply the first fraction by +%282y%29+%2F%282y%29+
+%28%284y%29%2F1+%2A+%282y%29%2F%282y%29%29+-+%281%2F+%282y%29+%29
%28+8y%5E2%29%2F%282y%29+-+1%2F+%282y%29+

Now subtract numerators, and place over the common denominator:
%288y%5E2+-+1%29+%2F%282y%29+
