Assume you mean:
3%2F%282y%29 - 3%2F%28%282y%2B4%29%29
:
Common denominator would be 2y(2y+ 4)
Over a single denominator, combine like terms ;
%283%282y%2B4%29+-+3%282y%29%29%2F%282y%282y%2B4%29%29 = %28%286y+%2B+12+-+6y%29%29%2F%282y%282y%2B4%29%29 = 12%2F%282y%282y%2B4%29%29 = 12%2F%28%284y%5E2%2B8y%29%29
Factor out 4
12%2F%284%28y%5E2%2B2y%29%29
Cancel into the 12
3%2F%28%28y%5E2%2B2y%29%29 or 3%2F%28y%28y%2B2%29%29
