计算 [（a-b）（a+b）]²÷（a²-2ab+b²）-2ab
计算 [（a-b）（a+b）]²÷（a²-2ab+b²）-2ab
计算 [（a-b）（a+b）]²÷（a²-2ab+b²）-2ab
[（a-b）（a+b）]²÷（a²-2ab+b²）-2ab
=(a-b)²(a+b)²/(a-b)²-2ab
=(a+b)²-2ab
=a²+b²
[（a-b）（a+b）]²÷（a²-2ab+b²）-2ab
= [（a-b）（a+b）]²÷（a-b)² - 2ab
= （a+b）² - 2ab
= a²+b²
[（a-b）（a+b）]²÷（a²-2ab+b²）-2ab
=(a-b)²(a+b)²÷(a-b)²-2ab
=(a+b)²-2ab
=a²+2ab+b²-2ab
=a平方+b平方
[（a-b）（a+b）]²÷（a²-2ab+b²）-2ab
=[（a-b）（a+b）]²÷（a－b﹚²-2ab
=﹙a＋b﹚²－2ab
=a²＋b²
