2/(a+2b) + 5/(3a-b) = 3/2 3/(a+2b) - 13/6 = 7/(b-3a)2/(a+2b) + 5/(3a-b) = 3/23/(a+2b) - 13/6 = 7/(b-3a)
2/(a+2b) + 5/(3a-b) = 3/2 3/(a+2b) - 13/6 = 7/(b-3a)
2/(a+2b) + 5/(3a-b) = 3/2
3/(a+2b) - 13/6 = 7/(b-3a)
2/(a+2b) + 5/(3a-b) = 3/2 3/(a+2b) - 13/6 = 7/(b-3a)2/(a+2b) + 5/(3a-b) = 3/23/(a+2b) - 13/6 = 7/(b-3a)
小朋友,这是很简单的题,自己做吧
5(a*a*b-3*a*a*b)-2*(a*a*b-7*a*b*b)
2(a+b)-[4(a+b)-3(a+b)]一[5(a-b)+(a-b)]过程
计算(5a-3b)^2+(a+b)(a-b)
2a+b/3a+5b 求a/b
已知a-b/a+b=-3,则代数式2(a-b)/a+b-5(a+b)/a-b=?
已知a-b/a+b=-3,则代数式2(a-b)/a+b-5(a+b)/a-b=?
(a+2b)(a-2b)+(a-b)(a+b)-2(a-3b)(a-b)
5a-3b-a+2b
(a-2b)(5a+3b)
a+a-a+2a-3a-2b+3b-5b+3b-4b-5b
因式分解(a-b)平方-3a+3b(a+b)(a-b)-2b(3a-5b)两个哈
因式分解(a-b)-3a+3b (a+b)(a-b)-2b(3a-5b)
(2a-3b)[(a+b)-b(a-3b)]
(2/3a)-[2/(a+b)]{[(a+b)/3a]-a-b}÷[(a-b)/b]
(2a+3b)^2-(a+5b)(a-5b)+(2a-3b)^2
(3a^2*b-7a*b^2-a^2*b^2)*5a*b化简
a^2+5(a-b)(a+b)-(3a-2b)^2+9b^2,化简
8a+2b+(5a - b) (5a-3b) -3 (a平方 - 2b)
