化简：｛(a2-4a+4)/(a2+2a+1)｝×｛（a+1）/（a²-4）｝化简：｛(a2-4a+4)/(a2+2a+1)｝×｛（a+1）/（a²-4）｝化简：｛(a2-4a+4

化简：｛(a2-4a+4)/(a2+2a+1)｝× ｛（a+1）/（a²-4）｝
化简：｛(a2-4a+4)/(a2+2a+1)｝× ｛（a+1）/（a²-4）｝

化简：｛(a2-4a+4)/(a2+2a+1)｝× ｛（a+1）/（a²-4）｝
｛(a2-4a+4)/(a2+2a+1)｝× ｛（a+1）/（a²-4）｝
=[(a-2)²/(a+1)²]×[(a+1)/[(a+2)(a-2)]]
=(a-2)/[(a+1)(a+2)]
