x^2-3xy-10y^2-3x+y+2 因式分解
x^2-3xy-10y^2-3x+y+2 因式分解
x^2-3xy-10y^2-3x+y+2 因式分解
x^2-3xy-10y^2-3x+y+2
=(x-5y)(x+2y)-3x+y+2
=(x-5y-2)(x+2y-1)
x^2-3xy-18y^2-3x-9y =(x-6y)(x+3y)-3(x+3y) =(x-6y-3)(x+3y) (x+3y)(x-6y)-3(x+3y) =(x+3y)(x-6y-3)
因式分解:12xy^2(y-x)+xy^3(x-y)+4x^2y(x-y)
X^Y-2XY^2+y^3
1、(-7x^y)(2x^y-3xy^3+xy) 2、((x-y)^6)/((y-x)^3)/(x-y)
化简:x-y/x+3y÷x^-y^2/x^2+6xy+9y^2-(xy/x+y)
因式分解 x-xy+3y-3x 2x+xy-y-4x+5y-6
[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)
-xy^2(x+y)^3+x(x+y)^2因式分解
(x+3y)/(x^2+xy)-x+y计算题
x*x+xy=3,xy+y*y=2,则x*x+2xy+y*y=________?
(x-2xy)*(-xy+2y*y)-(3x*x-2xy)(x-9xy+6y*y)答案应为-2x-x*x-3x,
x^2-xy-6y^2+3xy+y+2
(x+y)(x-y)-(2xy+3y)平方平方是(2xy+3y)的
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?
(-x+2y)(2x+y)-(2x+y)(y-2x)-3xy=?因式分解
x+y=-3 xy+x+y=-2 x/y+y/x=?
