(3x^2+2y-2y^2)·(-xy)^3要过程
(3x^2+2y-2y^2)·(-xy)^3
要过程
(3x^2+2y-2y^2)·(-xy)^3要过程
原式=(3x^2+2y-2y^2)·(-x^3y^3)
=-x^5y^3-2x^3y^4+2x^3y^5
X^Y-2XY^2+y^3
因式分解:12xy^2(y-x)+xy^3(x-y)+4x^2y(x-y)
x^2-xy-6y^2+3xy+y+2
2x²y-3(2xy-xy)-xy
(x+y)(x-y)-(2xy+3y)平方平方是(2xy+3y)的
x*x+xy=3,xy+y*y=2,则x*x+2xy+y*y=________?
(-x-y)(x^2+xy+y^2)
化简x^-y^/x^-2xy+y^
2*(x-y)²(y-x)(xy)
化简:x-y/x+3y÷x^-y^2/x^2+6xy+9y^2-(xy/x+y)
1、(-7x^y)(2x^y-3xy^3+xy) 2、((x-y)^6)/((y-x)^3)/(x-y)
因式分解 x-xy+3y-3x 2x+xy-y-4x+5y-6
(x^2y-9y)/(xy+3y)
(x^2+xy/x-y)/(xy/x-y)计算
化简:3x^2-[5xy-(x^y-3xy)+4x^2y-8xy]
若1/x-1/y=2,求3x-2xy-3y/x-xy-y的值3x-2xy-3y/x-xy-y 不好意思,是3x-2xy-3y/x-2xy-y
-xy^2(x+y)^3+x(x+y)^2因式分解
(xy^2-2xy+x)*y^3-y分之y^3+y^2
