是对的,刚才回答过了
计算:3a+4b/a-b+3b/b-a-4a/a-b
2(a+b)-[4(a+b)-3(a+b)]一[5(a-b)+(a-b)]过程
化简【3A方-(A+B)(B-A)】【4(-B-A)(B-A)+5B方】
(4a+3b)(3a+b)-(a+b)
(a-b)^10/(b-a)^4/(b-a)^3
(a-b)^10/(b-a)^4/(b-a)^3
(-3a+b)+(4a-3b)
(a+b)^3-4(a+b)
因式分解(a+b)^3-4(a+b)
(a-b)^3-4ab(b-a)
(a-b)^3-4ab(b-a)
(a-b)3-4ab(b-a)
(3a-6b)/(a+b) - (5a-6b)/(a-b) - (4a-5b)/(a+b) - (7a-8b)/(a-b) 快
(3a-6b/a+b)-(5a-6b/a-b)-(4a-5b/a+b)-(7a-8b/b-a)
计算:(4a-b)^2-[8a*(a-b)-(3a-b)*(3a+b)]
2a(a-b)+4a(2a+3b)
a+a-a+2a-3a-2b+3b-5b+3b-4b-5b
(3a+b)4b-[(2a+b+a-b)b]/2
