x+2y+4x^2y/4y^2+4y^2/x-2y结果是x^2/x+2yx+2y+4x^2y/4y^2+4y^2/x-2y结果是x^2/x+2yx+2y+4x^2y/4y^2+4y^2/x-2y结果是

x+2y+4x^2y/4y^2+4y^2/x-2y结果是x^2/x+2y
x+2y+4x^2y/4y^2+4y^2/x-2y
结果是x^2/x+2y

x+2y+4x^2y/4y^2+4y^2/x-2y结果是x^2/x+2y
x+2y+4y^2/(x-2y)=((x+2y)(x-2y))/(x-2y)+4y^2/(x-2y)=(x^2-4y^2)/(x-2y)+4y^2/(x-2y)=x^2/(x-2y) 或者是你的题说的有歧义
