分解因式:{-2(x-y)的2n次}-{4(y-x)的2n+1次}

分解因式:{-2(x-y)的2n次}-{4(y-x)的2n+1次}
分解因式:{-2(x-y)的2n次}-{4(y-x)的2n+1次}

分解因式:{-2(x-y)的2n次}-{4(y-x)的2n+1次}
{-2(x-y)的2n次}-{4(y-x)的2n+1次}
=﹣2(x-y)^2n +4(x-y)^2n*(x-y)
=2(x-y)^2n[﹣1+2(x-y)]
=2(x-y)^2n*(2x-2y-1)

-2(x-y)^2n-4(y-x)^(2n+1)
=-2(x-y)^2n+4(x-y)^(2n+1)
=(x-y)^2n[+4(x-y)-2]
