化简[(3a-4b)(-3a-4b)-(4b-3a)²-3a(1/3ab²+a-b)]÷(-3a)化简[(3a-4b)(-3a-4b)-(4b-3a)²-3a(1/3ab
化简[(3a-4b)(-3a-4b)-(4b-3a)²-3a(1/3ab²+a-b)]÷(-3a)
化简[(3a-4b)(-3a-4b)-(4b-3a)²-3a(1/3ab²+a-b)]÷(-3a)
化简[(3a-4b)(-3a-4b)-(4b-3a)²-3a(1/3ab²+a-b)]÷(-3a)
[(3a-4b)(-3a-4b)-(4b-3a)²-3a(1/3ab²+a-b)]÷(-3a)
=[(-4b+3a)(-4b-3a)-(4b-3a)²-3a(1/3ab²+a-b)]÷(-3a)
=[16b²-9a²-16b²+24ab-9a²-3a(1/3ab²+a-b)]÷(-3a)
=[24ab-18a²-3a(1/3ab²+a-b)]÷(-3a)
=6a-8b+1/3ab²+a-b
=7a-9b+1/3ab²
化简【3A方-(A+B)(B-A)】【4(-B-A)(B-A)+5B方】
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-{-2b[a-(4a+3b)]}
(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)]
化简：(a-3b)(a-3b-2)-a(a+3b-4)啊
[(4a+3b)(4a-3b)-(3a=3b)(2a-3b)]/5a 化简
