(2x^3y)^2×(-2xy)+(-2x^3y)^3÷(2x^2)
(2x^3y)^2×(-2xy)+(-2x^3y)^3÷(2x^2)
(2x^3y)^2×(-2xy)+(-2x^3y)^3÷(2x^2)
原式
=(2x^3y)^2×(-2xy)+(-2x^3y)^3÷(2x^2)
=(4x^6y^2)×(-2xy)+(-8x^9y^3)÷(2x^2)
=-8x^7y^3-4x^7y^3
=-12x^7y^3
(2x^3y)^2×(-2xy)+(-2x^3y)^3÷(2x^2)
=(4x^6y²)×(-2xy)+(-8x^9y³)÷(2x²)
=-8x^7y³-4x^7y³
=-12x^7y³
=4x^6y^2×(-2xy) -8x^9y^3÷2x^2
=-8x^7y^3-4x^7y^3
=-12x^7y^3
2x²y-3(2xy-xy)-xy
x^2-xy-6y^2+3xy+y+2
因式分解:12xy^2(y-x)+xy^3(x-y)+4x^2y(x-y)
X^Y-2XY^2+y^3
化简：3x^2-[5xy-(x^y-3xy)+4x^2y-8xy]
xy-2{xy-[3x^2y-(4xy^2+0.5xy)]+4x^2y}+6xy^2

x*x+xy=3,xy+y*y=2,则x*x+2xy+y*y=________?
x^2-xy/xy-y^2约分
(x-2xy)*(-xy+2y*y)-(3x*x-2xy)(x-9xy+6y*y)答案应为-2x-x*x-3x，
（x^2+xy/x-y)/（xy/x-y)计算
因式分解 x-xy+3y-3x 2x+xy-y-4x+5y-6
