(a2+2ab+b2)2÷(-a-b)3(a²+2ab+b²)²÷(-a-b)³才对(a2+2ab+b2)2÷(-a-b)3(a²+2ab+b

(a2+2ab+b2)2÷(-a-b)3(a²+2ab+b²)²÷(-a-b)³ 才对
(a2+2ab+b2)2÷(-a-b)3
(a²+2ab+b²)²÷(-a-b)³ 才对

(a2+2ab+b2)2÷(-a-b)3(a²+2ab+b²)²÷(-a-b)³ 才对
=(a+b)的4次方÷[-(a+b)³]
=-(a+b)
=-a-b

(a2+2ab+b2)2÷(-a-b)3
=((a+b)^2)^2÷[-(a+b)^3]
=(a+b)^4÷[-(a+b)^3]
=-(a+b)

﹙a²+2ab+b²﹚÷﹙﹣a-b﹚³
=﹣﹙a+b﹚²÷﹙a+b﹚³
=﹣1/﹙a+b﹚

(a²+2ab+b²)²÷(-a-b)³ =-a-b
