I am going to assume that it is
%281-y%29%2F%284y%2B4%29%2A+%28y%2B1%29%2F%28y%2B4%29
even though you didn't include the proper ()
as in (1-y)/(4y+4)* (y+1)/(y+4)
%281-y%29%2F4%28y%2B1%29%2A+%28y%2B1%29%2F%28y%2B4%29
%281-y%29%2F4cross%28y%2B1%29%2A+cross%28y%2B1%29%2F%28y%2B4%29
%281-y%29%2F%284%2A%28y%2B4%29%29

1-y/4y+4 times y+1/y+4 = [1-(y/y+4)][y+1/y+4]
= [(y+4-y)/y+4][y(y+4)+1]/(y+4)
= 4[y^2+4y+1]/(y+4)^2
