化简:a^2+2a/a^2-6a+9÷a^2-4/a^2-3a-a/a-2化简:a^2+2a/a^2-6a+9÷a^2-4/a^2-3a-a/a-2化简:a^2+2a/a^2-6a+9÷a^2-4/a
化简:a^2+2a/a^2-6a+9÷a^2-4/a^2-3a-a/a-2
化简:a^2+2a/a^2-6a+9÷a^2-4/a^2-3a-a/a-2
化简:a^2+2a/a^2-6a+9÷a^2-4/a^2-3a-a/a-2
a^2+2a/a^2-6a+9÷a^2-4/a^2-3a-a/a-2
=a(a+2)/(a-3)^2×a(a-3)/(a+2)(a-2)-a/(a-2)
=(a^2)/(a-3)(a-2)-a/(a-2)
=[a^2-a(a-3)]/(a-3)(a-2)
=3a/(a-3)(a-2)
化简; a-2a+3a-4a+5a-6a+``````-2006a+2007a.
化简:a-2a+3a-4a+5a-6a+.+2010a+2011a.
化简:81-a²/a²+6a+9÷a-9/2a+6 +a+15/a+3
化简(a/a-2-a/a+2)×4-a/a(a/a-2-a/a+2)×4-a/a
化简:a^2+2a/a^2-6a+9÷a^2-4/a^2-3a-a/a-2
a-2a+3a-4a+5a-6a+7a-8a+9a-10a+11a.+99a-100a=
化简(a/a-2-a/a+3)*a^2+a-6/a
[(a^2-9)/(a^2-6a+9)+(3-a)/(a+3)]×(a-3)/a
化简:2A+0.5A-6A
分式的乘除:16-a平方/a平方+8a+16÷a-4/2a+8乘a-2/a+281-a平方/a平方+6a+9÷a-9/2a+6乘a+3/a+9
(4-2a)(a^2-6a+9)÷(3a-a^2)(a^2+2a-15)今天就要
a^2+6a+9分之a+2÷(a+2)*2-a分之(a+3)(a-2)=
3a-[(a^2+4a+4)/(a+2)]+[(a^2+6a+9)/(a+3)] 化简 快加
81-a²/a²+6a+9÷a-9/2a+6×a+3/a+9 计算
9-a^2/a^2+6a+9÷a^3-3a/a+3+1/a..算算吧
2a+a²/a-a 化简.(2a+a²/a)-a
a-2a+3a-4a+5a-6a+...+99a-100a
(a+3a+5a+...+2009a)-(2a+4a+6a+...+2008a)=
