3x^3+6x^2y+3xy^2
3x^3+6x^2y+3xy^2
3x^3+6x^2y+3xy^2
提取3x:3x(x+2xy+y)=3x(x+y)
(x-2xy)*(-xy+2y*y)-(3x*x-2xy)(x-9xy+6y*y)答案应为-2x-x*x-3x,
(x+2y-3xy)-(-2x-y+xy),其中x+y=,xy=-,求值.
因式分解 x-xy+3y-3x 2x+xy-y-4x+5y-6
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)
x^2-xy-6y^2+3xy+y+2
3xy(x^2y-xy^2+xy)-xy^2(2x^2-6xy+2x)过程
(X-3xy+4xy-y)-[-2x-2(xy-3/2xy)-y]+6xy的过程
xy-2{xy-[3x^2y-(4xy^2+0.5xy)]+4x^2y}+6xy^2
5x^3y*(-3y)^2+(-6xy)^2*(-xy)+xy^3*(-4x^2)
因式分解:12xy^2(y-x)+xy^3(x-y)+4x^2y(x-y)
因式分解x^4y-x^2y^3+x^3y^2-xy^4
x^2+xy-6y^2-3x+6y
2x^2+3xy+y^2+x-y-6
x²+3xy+2y-x+y-6因式分解
因式分解xy+6-2x-3y
因式分解xy+6-2x-3y
化简分式方程:x*x-xy-y*y/x*x-3x-6y+2xy
