(x^3+xy^2+1)/(x^3+xy^2-x^2y-y^3)×(x^2y-xy^2)/(x^3+xy^2-x^2y-y^3)+_数学解答

(x^3+xy^2+1)/(x^3+xy^2-x^2y-y^3)×(x^2y-xy^2)/(x^3+xy^2-x^2y-y^3)+(x^2y+y^2)/(x^3+xy^2+x^2y+y^3)×(x^2y+y^3+1)/(x^2y+y^3-x^3-xy^2)+(x^3+y^3)/(x^3+xy^2+x^2y+y^3)简化为最简结果

解答

看了一下题,(x^3+xy^2+1)/(x^3+xy^2-x^2y-y^3)×(x^2y-xy^2)/(x^3+xy^2-x^2y-y^3),两个分母居然也是一样的,而且x^2y+y^2这样的次数,我总觉得题目是不对的...
