我怕了你了,今天怎么都是你的题目.拜托,把题目分开一点,好不好?
(a+2b)(a-2b)+(a-b)(a+b)-2(a-3b)(a-b)
5(a*a*b-3*a*a*b)-2*(a*a*b-7*a*b*b)
(2a-3b)[(a+b)-b(a-3b)]
(2/3a)-[2/(a+b)]{[(a+b)/3a]-a-b}÷[(a-b)/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
a^2(a-b)+b^2(b-a) 因式分解 (a-b)^3-(a-b)^2 因式分解
2(a+3b)²-8(a+b)(a-b)-(a+3b)(a-b)
A-B A+B 2B+A 3A-B 6A+2B
化简a/b(a-b)-b/a(a-b)其中a=3 b=-2
2(a+b)-[4(a+b)-3(a+b)]一[5(a-b)+(a-b)]过程
（（a+2b)+(2a+3b))*(a+b)/2
2a(a-3b)-b(3b-a)
(3a+b)*(a-2b)*(2a+b)
(3a+2b)*(2a+b)*(a+b)=
计算（a-b)(b-a)^3+[(a-b)^2]^2
a/a-b 3b/2a-2b 通分
2a(a-b)-3b(2a-b)咋做化简！！！
