x³-x ²y-xy ²+y³怎么因式分解
x³-x ²y-xy ²+y³怎么因式分解
x³-x ²y-xy ²+y³怎么因式分解
x2(x-y)-y2(x-y)
(x2-y2)(x-y)
(x-y)2(x+y)
x2(x-y)-y2(x-y)=(x2-y2)(x-y)=(x+y)(x-y)2
=(x3+y3)-(x2y+xy2)
=(x+y)(x2-xy+y2)-xy(x+y)
=(x+y)(x2-xy+y2-xy)
=(x+y)(x2-2xy+y2)
=(x+y)(x-y)2
x³-x ²y-xy ²+y³=x ²(x-y)+y ²(y-x)=(x-y)(x ²-y ²)=(x+y)(x-y)²
x³y³-x²y²-xy+1
x³-x²y-xy²+y³(因式分解)
3x³ - 6x²y+ 3xy²
因式分解 4xy²-4x²y-y³
6xy²-9x²y-y³
6xy²-9x²y-y³因式分解
6xy²-9x²-y³
x³-x ²y-xy ²+y³怎么因式分解
降幂的题,x³-y³+3x²y-4xy²=
计算 ①[x(x²y²-xy)-y(x²-x³y)]÷3x²y
计算:[x(x²y²-xy)-y(x²-x³y)]÷3x²y
[x(x²y²-xy)-y(x²-x³y)]÷3x²y
计算:-2y³+(3xy²-x²y)-2(xy²-y³)
(1/3xy)²*(-12x²y²)÷(-4/3x³y)
16x²-64 y³4xy²+4x²y
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
