1.(x-y)(x^2+xy+y^2) 2.(3x+2y)(2x+3y)
1.(x-y)(x^2+xy+y^2)
=x³+x²y+xy²-x²y-xy²-y³
=x³-y³
2.(3x+2y)(2x+3y)
=6x²+9xy+4xy+6y²
=6x²+13xy+6y²
1. (x-y)(x^2+xy+y^2) =x^3+y*x^2+x*y^2-y*x^2-x*y^2-y^3=x^3-y^3
2. (3x+2y)(2x+3y)=6x^2+9xy+4xy+6y^2=6x^213xy+6y^2
(-x-y)(x^2+xy+y^2)
化简x^-y^/x^-2xy+y^
2*(x-y)²(y-x)(xy)
（x^2+xy/x-y)/（xy/x-y)计算
X-Y/2X+2Y XY/X+Y²
因式分解：x×x-xy-2y×y-x-y
1.（xy-1）^2-(x+y-2xy)(2-x-y)2.(x+y)(x+y+2xy)+(xy-1)(xy+1)
因式分解:12xy^2(y-x)+xy^3(x-y)+4x^2y(x-y)
(x-y)[(x+y)^2-xy]+(x-y)[(x-y)^2+xy]
.(x+y-2)(x+y-2xy)+(xy-1)^2
(x^2-xy)y÷y-x/xy怎么做?
代数 x^-y^/ x^-(y-z)^ 除以 x^+2xy+y^/(x-y)^-z^ 乘 x^+xy-xz/x^-xy
(x+y)/x /(x-(2xy-y^2)/x) 因式分解
x^2-xy/xy-y^2约分
(x+y)(x+y+2xy)+(xy+1)(xy-1)(x+y)(x-y)+4(y-1)
（y/(x^2-xy)+x/(y^2-xy))除以(x-y)/(xy)
x^2y-2xy+y化简
X^Y-2XY^2+y^3
