化简(2a-b/a+b-b/a-b)÷a-2a/a-b化简(2a-b/a+b-b/a-b)÷a-2a/a-b化简(2a-b/a+b-b/a-b)÷a-2a/a-b(2a-b/a+b-b/a-b)除以a
化简(2a-b/a+b-b/a-b)÷a-2a/a-b
化简(2a-b/a+b-b/a-b)÷a-2a/a-b
化简(2a-b/a+b-b/a-b)÷a-2a/a-b
(2a-b/a+b-b/a-b)除以a-2b/a+b
=[(2a-b)(a-b)-b(a+b)]/(a+b)(a-b)x(a+b)/(a-2b)
=(2a²-3ab+b²-ab-b²)/(a-b)(a-2b)
=2a(a-2b)/(a-b)(a-2b)
=2a/(a-b)
满意请采纳、谢谢
化简(2a-b/a+b-b/a-b)÷a-2a/a-b
化简:{[(2a-b)/(a+b)]-[b/(a-b)]}÷[(a-2b)/(a+b)]
化简:|a+b|+|b-a|+|2b|
化简(2a-b/a+b-b/a-b)除以a-2b/a+b
化简(2a-b/a+b-b/a-b)除以a-2b/a +b
化简|a|+|-b|-|a-b|-|a+b|
化简 |b|-|a|+|a-b|+|a+b|
化简 |a-b|+|a+b|-|a-b|
(a-b)^2-2(a-b)(a+b)+(a+b)^2 化简(a-b)^2-2(a-b)(a+b)+(a+b)^2化简
化简:a-[b-2a-(a-b)]
-2a(a+b)+b(a+b)
(2/3a)-[2/(a+b)]{[(a+b)/3a]-a-b}÷[(a-b)/b]
化简 a(a-2b)+2(a+b)(a-b)+(a+b)²
化简:[2/3a - 2/(a+b) * (a+b/3a - a - b)] / (a-b)/a
(2/3a)-[2/(a+b)]{[(a+b)/3a]-a-b}÷[(a-b)/a]
(a+b分之2a-b - a-b分之b)÷ a+b分之a-2b
(a+b).(a-b)
