因式分解: x(x+y)(x-y)-x(x+y)²(x-y)= x(m-n)³-x²(n-m)²= 4m(x-y
因式分解:x(x+y)(x-y)-x(x+y)²(x-y)=x(m-n)³-x²(n-m)²=4m(x-y)-2m²(y...
因式分解:

x(x+y)(x-y)-x(x+y)²(x-y)
=x(x+y)(x-y)-x(x+y)²(x-y)
=x(x+y)(x-y)[1-(x+y)]
=x(x+y)(x-y)(1-x-y)
x(m-n)³-x²(n-m)²
=x(m-n)³-x²(n-m)²
=x(m-n)³-x²(m-n)²
=x(m-n)²[(m-n)-x]
=x(m-n)²(m-n-x)
4m(x-y)-2m²(y-x)³
=4m(x-y)-2m²(y-x)³
=4m(x-y)+2m²(x-y)³
=2m(x-y)[2+m(x-y)²]
=x(x+y)(x-y)-x(x+y)²(x-y)
