化简:【(x²-4)/(x²-4x+4)-1/(x-2)】*(x²-2x)/(x+1)快啊,急用

化简:【(x²-4)/(x²-4x+4)-1/(x-2)】*(x²-2x)/(x+1)快啊,急用
化简:【(x²-4)/(x²-4x+4)-1/(x-2)】*(x²-2x)/(x+1)
快啊,急用

化简:【(x²-4)/(x²-4x+4)-1/(x-2)】*(x²-2x)/(x+1)快啊,急用
原式=[(x+2)(x-2)/(x-2)²-1/(x-2)]*x(x-2)/(x+1)
=[(x+2)/(x-2)-1/(x-2)]*x(x-2)/(x+1)
=(x+2-1)/(x-2)*x(x-2)/(x+1)
=(x+1)/(x-2)*x(x-2)/(x+1)
=x

【(x²-4)/(x²-4x+4)-1/(x-2)】*(x²-2x)/(x+1)
=【(x-2)(x+2)/(x-2)²-1/(x-2)】*x(x-2)/(x+1)
=【(x+2)/(x-2)-1/(x-2)】*x(x-2)/(x+1)
=【(x+2)-1】*x/(x+1)
=x


[(x²-4)/(x²-4x+4)-1/(x-2)]*(x²-2x)/(x+1)
=[(x+2)(x-2)/(x-2)²-1/(x-2)]*x(x-2)/(x+1)
=[(x+2)/(x-2)-1/(x-2)]*x(x-2)/(x+1)
=[(x+1)/(x-2)]*x(x-2)/(x+1)
=x
