x^3-4y^3+x^2y-4xy^2
x^3-4y^3+x^2y-4xy^2
x^3-4y^3+x^2y-4xy^2
x^3-4y^3+x^2y-4xy^2
=x^3+x^2y-4y^3-4xy^2
=x²(x+y)-4y²(x+y)
=(x+y)(x²-4y²)
=(x+y)(x+2y)(x-2y)
因式分解:12xy^2(y-x)+xy^3(x-y)+4x^2y(x-y)
因式分解 x-xy+3y-3x 2x+xy-y-4x+5y-6
化简：3x^2-[5xy-(x^y-3xy)+4x^2y-8xy]
化简2(x²y+xy)-3(x²y-xy)-4x²y
（-3x^y+2xy)-( )=4x^+xy
x²/xy-x/y 3x/4x+y - x-2y/4x+y (1-y/y+x)÷x/y²-x²
x²-y²+5x+3y+4（x+y-2xy)(x+y-z)+(xy-1）²
x^3y(-4y)^2+(-7xy)^2*(-xy)-5xy^3*(-3x)^2
5x^3y*(-3y)^2+(-6xy)^2*(-xy)+xy^3*(-4x^2)
x^2-4xy+3y^2=（x-3y)(x-y)x^2-4xy+3y^2 怎么分解成（x-3y)(x-y)
3(x^2y+xy)-4(xy-2x^2y)-(-xy)
当x-y=2xy时,求4x-3xy-4y/xy
XY(XY+3)+(XY+4)+4(X+Y+1)-(X+Y+2)
3（x平方y+xy)-4(xy-2x平方y)-(xy)
化简：2x²y+{2xy-[3x²y-2(-3x²y+2xy)]-4xy}化简：2x²y+{2xy-[3x²y-2(-3x²y+2xy)]-4xy}
因式分解：x(y-3)-(2y-6) (x+y)^3-(x-y)^2(x+y) x(x^2-xy)-(4x^2-4xy)
分解公因式分解 x(y-3)-(2y-6) 2.(x+y)^3-(x-y)^2(x+y) 3.x(x^2-xy)-(4x^2-4xy)
xy-2{xy-[3x^2y-(4xy^2+0.5xy)]+4x^2y}+6xy^2
