2x^2+3xy-2y^2-x+8y-6分解因式用双十字相乘2x^2+3xy-2y^2-x+8y-6分解因式用双十字相乘2x^2+3xy-2y^2-x+8y-6分解因式用双十字相乘原式=2x^2+(3
2x^2+3xy-2y^2-x+8y-6分解因式 用双十字相乘
2x^2+3xy-2y^2-x+8y-6
分解因式 用双十字相乘
2x^2+3xy-2y^2-x+8y-6分解因式 用双十字相乘
原式=2x^2+(3y-1)x-2(y^2-4y+3)=2x^2+(3y-1)x-(2y-2)(y-3)=(x+2y-2)(2x-y+3).
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-2xy)*(-xy+2y*y)-(3x*x-2xy)(x-9xy+6y*y)答案应为-2x-x*x-3x,
诺x+y=6,xy=4 求(5x-4y-3xy)-(8x-y+2xy)
x^2-xy-6y^2+3xy+y+2
化简:3x^2-[5xy-(x^y-3xy)+4x^2y-8xy]
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?
因式分解:12xy^2(y-x)+xy^3(x-y)+4x^2y(x-y)
2x^2+3xy+y^2+x-y-6
x^2+xy-6y^2-3x+6y
x²+3xy+2y-x+y-6因式分解
X^Y-2XY^2+y^3
已知xy=-2,x-y=3,求(x+y)(x-y)-y^2+(x-y)^2-(6x^2y-2xy^2)÷2y
3(x-y)²-7(x-y)+8(x-y)²+6(x-y)求详细过程(2) 5xy-4x²y-8xy²+3xy-xy²+4x²y
(8X^3Y-6X^2Y^2-2XY^3)/(3XY)
(8X^3Y-6X^2Y^2-2XY^3)/(3XY)
5x^3y*(-3y)^2+(-6xy)^2*(-xy)+xy^3*(-4x^2)
