(x+y)³÷(x+y)·(x+y)²
求因式分解(x-y)²-2(x-y)³和(x+y)(x-y)-x(x-y)
2.(x+y)²(x-y)²-(x-y)(x+y)(x²+y²)
[x(x²y²-xy)-y(x²-x³y)]÷3x²y
因式分解:[x(x²y²-xy)-y(x²-x³y)]÷3x²y
因式分解 -5x³y(x-y)³+20y【x²(y-x)】²
(x-y)³(y-x)(y-x)²+(x-y)^6
(x-y)的四次方(x-y)-2(x-y)²(y-x)³等于?
计算4(x+y)^5(x-y)^4÷[2(x+y)³*(y-x)²]
计算:①-x·(y-x)³·(x-y)的四次方 ②(x-y)²·(y-x)³·(x-y)的
1/2 x²y·( )=2x³y-x²y²
{(x-y)²+(x+y)(x-y)}÷2x
已知x²-y²=10,求[(x+y)³-2y(x+y)²-4(x+y)]÷(x+
