(4x^2y+x^3y^3)÷(-2x^2y)计算
(4x^2y+x^3y^3)÷(-2x^2y)计算
(4x^2y+x^3y^3)÷(-2x^2y)计算
(4x^2y+x^3y^3)÷(-2x^2y)=-2-1/2xy^2
(4x²y+x³y³)÷(-2x²y)
=-2-xy²/2
x²/xy-x/y 3x/4x+y - x-2y/4x+y (1-y/y+x)÷x/y²-x²
化简3x-2/(x+y)[(x+y)/3x-x-y]÷(x-y)/x
4x-3y/x-2y÷6y-8x/y-2x
(y-x)^4(x-y)^3+2(x-y)^6(y-x)
(x-y)^3×(y-x)^4+(x-y)^2×(y-x)^5
(x+y)/2- x-y/2=6 3(x+y)=4(x-y)
12(x+y)^3(y-x)/【4(x+y)^2(x-y)】
2分之x+y+3分之x-y;4(x+y)-(x-y)谢谢了,
2(x-y)²-3(x-y)(-y-x)
(x-y) (x-2y)+(x+2y) (x-3y)-2(x-3y) (x-4y)=
1.(x^3-x^2-4x+1)/(x^2-3x+2)-(x^3-2x^2-9x+21)/(x^2-5x+6)+(x^2-3x+8)/(x^2-4x+3)2.{(x^2)/(x-y)}*{y/(x+y)}-{(x^4y)/(x^4-y^4)}÷{(x^2/x^2+y^2)^2}
x(x-y)2-(y-x)3
(x+3y-4)(2x-y)
计算(2x-3y)(x+4y)-(3x+y)(x-2y)(2x-3y)(x+4y)-(3x+y)(x-2y)
因式分解(x-2y)(x-3y)+(x-4y)(x-5y)+(x-3y)(x-5y)+(x-2y)(x-4y)
(x+y)-(x-y)^3÷(x-y)(x+y)×2y化简e ,
已知x-y=1,求[(x+2y)²+(2x+y)(x-4y)-3(x+y)(x-y)]÷y的值
[2/3x-2/x+y(x+y/3x-x-y)]/x-y/x
