化简:[2/3a - 2/(a+b) * (a+b/3a - a - b)] / (a-b)/a
化简:[2/3a - 2/(a+b) * (a+b/3a - a - b)] / (a-b)/a
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
=[2/3a-2/(a+b)*(a+b)*(1/3a-1)]/(a-b)/a
=a[2/3a-2(1/3a-1)]/(a-b)
=a*2/(a-b)
=2a/(a-b)
[2/3a - 2/(a+b) * (a+b/3a - a - b)] / (a-b)/a
=[2/3a-2/3a+2]/(a-b)/a
=2/(a-b)/a
=2a/(a-b)
=[2/3a-2/(a+b)*(a+b)*(1/3a-1)]/(a-b)/a
=a[2/3a-2(1/3a-1)]/(a-b)
=a*2/(a-b)
=2a/(a-b)
化简:[2/3a - 2/(a+b) * (a+b/3a - a - b)] / (a-b)/a
化简a/b(a-b)-b/a(a-b)其中a=3 b=-2
化简 (a+b)²+2a(a-1/2b)-3(a-b)(a+b)
5(a*a*b-3*a*a*b)-2*(a*a*b-7*a*b*b)
(a+2b)(a-2b)+(a-b)(a+b)-2(a-3b)(a-b)
化简：a-[b-2a-(a-b)]
(2/3a)-[2/(a+b)]{[(a+b)/3a]-a-b}÷[(a-b)/a]
