(xy-x²)³-x³(y-x)因式分解 帮一下吧
(xy-x²)³-x³(y-x)因式分解 帮一下吧
(xy-x²)³-x³(y-x)因式分解 帮一下吧
(xy-x²)³-x³(y-x)=[x(y-x)]³-x³(y-x)
=x³(y-x)³-x³(y-x)=x³(y-x)[(y-x)²-1]
=x³(y-x)[(y-x)-1][(y-x)+1]
=x³(y-x)(y-x-1)(y-x+1)
(xy-x²)³-x³(y-x)
=x³(y-x)³-x³(y-x)
=x³(y-x)[(y-x)²-1]
=x³(y-x)(y-x-1)(y-x+1)
(xy-x²)³-x³(y-x)因式分解 帮一下吧
x³y³-x²y²-xy+1
x³-x²y-xy²+y³(因式分解)
已知x,y满足x²+y²-4x-6y+13=0,求(-y/x³)³÷(-1/xy)四次方×(x/y²)²
(x+3y)²+(2x+6y)(3y-4x)+(4x-3y)²还有几题:a四次方-6a²-27—56x³yz+14x²y²z-21xy²z²5m(x-y)²+10n(y-x)³
计算:-2y³+(3xy²-x²y)-2(xy²-y³)
计算:3x²y×(-2xy³)
几道因式分解 (1)x³+x²+2xy+y²+y³(2)x³+3x²y+3xy²+y³(3)x³-3x²y+3xy²-y³(4)x³+3x²+3x+2
[(-2x)² y+8(-xy)³ -4(x²)]÷2x是[(-2x)² y+8(-xy)³ -4(x²)³]÷2x
有这样一道计算题:“计算(2x³-3x²y-2xy²)-(x³-2xy²+y³)+(-x&su甲同学把x=1/2错看成x=-1/2,但计算结果仍正确,你说是怎么一回事?后面是+(-x³+3x²y-y³)
3x³ - 6x²y+ 3xy²
x³+2xy-x-xy²=(因式分解)
分别以XY为半径画同心圆(X>Y),所得圆环的面积为14π,求式子[-6(x+y)²(x-y)³]²÷[3(x求式子[-6(x+y)²(x-y)³]²÷[3(x +y)(x-y)²]²
|x-2|+(y+1/4)^2=0 初一数学 速度……|x-2|+(y+1/4)^2=0,试求代数式x²(x²-xy+y)-x(x³-2x²+xy-1)的值已知xy²=-2,求-xy(x³y²-3x²y^5-y)的值
分解因式①x³-3x+2;②3x²-11xy+6y²-xz-4yz-2z²;③a²(b-c)+b²
