18x^2(x-2y)^2+24xy(2y-x)^2-12x(2y-x)^3
18x^2(x-2y)^2+24xy(2y-x)^2-12x(2y-x)^3
18x^2(x-2y)^2+24xy(2y-x)^2-12x(2y-x)^3
原式=18x^2(2y-x)^2+24xy(2y-x)^2-12x(2y-x)^3
=6x(2y-x)^2[3x+4y-2(2y-x)]
=6x(2y-x)^2(3x+4y-4y+2x)
=6x(2y-x)^2*5x（乘号严格来说应该是一点,但不知道怎么用键盘输出,在此说明一下.）
=30x^2(x-2y)^2
（x^2+xy/x-y)/（xy/x-y)计算
(-x-y)(x^2+xy+y^2)
化简x^-y^/x^-2xy+y^
2*(x-y)²(y-x)(xy)
x^2-xy/xy-y^2约分
.(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
(xy-x²)÷(x²-2xy+y²/xy)×（x-y/x²）
x-y/x²÷x²-2xy+y²/xy*（xy-x²）
X-Y/2X+2Y XY/X+Y²
因式分解：x×x-xy-2y×y-x-y
（y/(x^2-xy)+x/(y^2-xy))除以(x-y)/(xy)
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]
因式分解18x^2(x-2y)^2-24xy(2y-x)^2-12x(2y-x)^3
18x^2(x-2y)^2+24xy(2y-x)^2-12x(2y-x)^3
