a(a+b)(a-b)-a(a-b)^2
=a(a+b)(a-b)-a(a-b)(a-b)
=a(a-b)[(a+b)-(a-b)]
=a(a-b)(a+b-a+b)
=ab^2(a-b)

a(a-b){(a+b)-2}

提a(a-b)
a(a+b)(a-b)-a(a-b)^2
=a(a-b)[(a+b)-(a-b)]
=2ab(a-b)

2ab(a-b)

-2a(a+b)+b(a+b) (a+b).(a-b) a/b-b/a a+b>a-b, a-b>a,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] 化简:[2/3a - 2/(a+b) * (a+b/3a - a - b)] / (a-b)/a 化简（2a-b/a+b-b/a-b）÷a-2a/a-b (2/3a)-[2/(a+b)]{[(a+b)/3a]-a-b}÷[(a-b)/b] (a/a-b-a/a+b)(a+b)(a-b)/2b (b-a)*(b-a)+(b-a)*2*a等于多少? 2a*a-(a+a+2b)*(a-b)/2 因式分解：a×a×a-2a×a×b+ab×b -a-b+2b^2/a+b 化简：|a+b|+|b-a|+|2b|
