=5/4a³+2a^5-3/2b²
(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)
已知A=5a-3b,B=-6a+4b,A-B=?
初二分式的加减法2a-b-c/(a-b)(a-c)+ 2b-c-a/(b-c)(b-a)+ 2c-b-a/(c-b)(c-a)3a-6b/a+b- 5a-6b/a-b- 4a-5b/a+b+ 7a-8b/b-a注:有空格的地方是下一个分式
已知A=5a-3b,B=-6a+4b,则A-B等于 A.-a+b,B=11a+b C.11a-7b D -a-7b
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】

(12a^4b^5-4a^8b^3-6a^2b^3)/2a^2b^3
(3a-4b)(5a-6b)+(7a-8b)(5a-6b)分解因式得
(3a-4b)(5a-6b)+(7a-10b)(5a-6b)分解因式得?
(a^2+1)(-4a^2+1)+a^4-1 3a(a-b)(a+b)-6(b-a)^2a^2-9(a-b)^2= 3a(a-b)(a+b)-6(b-a)^2=
3(a+b)的平方-6(a+b)-4(a+b )的平方+5(a+b)-47
