3y/x*x-y*y+x/x*x-2xy+y*y+6y*y/x*x*x-x*x*y-xy*y+y*y*y等于多少?
3y/x*x-y*y+x/x*x-2xy+y*y+6y*y/x*x*x-x*x*y-xy*y+y*y*y等于多少?
3y/x*x-y*y+x/x*x-2xy+y*y+6y*y/x*x*x-x*x*y-xy*y+y*y*y等于多少?
3y/(x^2-y^2)+x/(x^2-2xy+y^2)+6y^2/(x^3-x^2y-xy^2+y^3)
=3y/[(x+y)(x-y)]+x/(x-y)^2+6y^2/[(x-y)^2(x+y)]
=3y(x-y)/[(x-y)^2(x+y)]+x(x+y)/[(x-y)^2(x+y)]+6y^2/[(x-y)^2(x+y)]
=[3y(x-y)+x(x+y)+6y^2]/[(x-y)^2(x+y)]
=(x^2+4xy+3y^2)/[(x-y)^2(x+y)]
=(x+3y)(x+y)/[(x-y)^2(x+y)]
=(x+3y)/(x-y)^2
因式分解:12xy^2(y-x)+xy^3(x-y)+4x^2y(x-y)
[x(x^2y^2-xy)-y(x^2-x^3y)]/3x^2y
[x(x^2y^2-xy)-y(x^2-x^3y)]/3x^2y
[x(x^2y^2-xy)-y(x^2-x^3y)]/(2x^2y)
