(xy-x²)³-x³(y-x)因式分解 帮一下吧
有这样一道计算题:“计算(2x³-3x²y-2xy²)-(x³-2xy²
已知x,y满足x²+y²-4x-6y+13=0,求(-y/x³)³÷(-1/xy
x³y³-x²y²-xy+1
七年级数学题(x-y)³ ×(x-y)²×(y-x)
数学整式除法计算:(1)(7x²y³-8x²y³z)÷8x²y&sup
1已知X-Y=XY=3求(X+Y)²及X³-Y³的值
因式分解:m³-2m²-4m+8;x²-2xy+y²-9
化简再求值 4x³(-y³)²-3x×(-x)²(-y²)³
若(x-5)²=169,(y-1)³=-0.125,求根号x-根号2xy-立方根2y-x
已知x(½)+x(-½)=3,计算[x(³/²)+x(-³/&
说明理由(5x³-7x³y+3x³y)+2x³-(-7x³y+3x&s
解决下列因式分解1、xy²-2xy+x³2、25x四次方-(x²-4xy)²
