初中因式分解：(x+y-2xy)(x+y-2)+(1-xy)^2
步骤一定要详细!不然我看不懂~

(x+y-2xy)(x+y-2)+(1-xy)^2
=(x+y)^2-2(x+y)-2xy(x+y)+4xy+(1-xy)^2
=(x+y)^2-2(x+y)(1+xy)+(1+xy)^2
=(x+y-xy-1)^2

初中因式分解：(x+y-2xy)(x+y-2)+(1-xy)^2 （xy-x-y+1)^2因式分解因式分解xy+y平方+x-y-2 y^3+xy^2+2xy+x^2-1 因式分解因式分解xy²-2xy+x+2y-1 x^2+y^2-x-y-xy+1如何因式分解因式分解：x×x-xy-2y×y-x-y 几道初中因式分解(XY)^2+2XY+1-(X+Y)^2(2X-3Y)^3+(3X-2Y)^3-125(X-Y)^3(X 因式分解:-x^2+2xy-y^2 xy+2x+y+2因式分解因式分解:x^2y+xy^2=? 因式分解 2x^+xy-6y^
