(12a^4b^5-4a^8b^3-6a^2b^3)/2a^2b^3
(a+2b)(2a+4b)(3a+6b)(4a+8b)
1.(a-b)^2(b-a)^3(a-b)^-4
(3a-6b)/(a+b) - (5a-6b)/(a-b) - (4a-5b)/(a+b) - (7a-8b)/(a-b
(3a-6b/a+b)-(5a-6b/a-b)-(4a-5b/a+b)-(7a-8b/b-a)
如果a-2b/a+2b=3,求a+2b/a-2b+3a-6b/4a+8b
(a-2b)/(a+2b)=3,求(a+2b)/(a-2b)+(3a-6b)/(4a+8b)的解,
因式分解8a^3b^3 12a^4b^2 16a^5b
0 a a+b 2a+b 2a+2b 3a+2b 3a+3b 4a+3b 4a+4b 5a+4b 5a+5b …… 求一
3a^2b-{2a^2b+[9a^b-(6a^2b+4a^2)]-(3a^2b-8a^2)}=
(2a+b)(2a-b)-3a(4a-3b)+(4a-b)(2a-b) a=5分之3,b=3分之2
(3a+2b)(6a-5b)(2b-3a)(5a+6b)
8a+2b+(5a - b) (5a-3b) -3 (a平方 - 2b)
