[a/(a-1)+a/(a+2)](a+2)/(2a平方+3a+1)化简
(a 1)(a 2)(a 3)(a
(a+2)(a+1)-a(a-3)
化简(a+1)(a-2)/(a+2)(a-2)+3
化简 3a-[5a-(a+2)+a]-1
化简; a-2a+3a-4a+5a-6a+``````-2006a+2007a.
化简:a-2a+3a-4a+5a-6a+.+2010a+2011a.
化简:a(a*a-1)+2a*a(a+1)-3a(2a-5)拜托了各位
a(a-1)(a-2)(a-3)(a-4)因式分解
化简:(a^3-a^2-a+1)/(a^3-3a^2+3a-1)
(a^3 - a^2 - a + 1)/(a^3 - 3a^2 + 3a - 1) 化简.
化简1/(a+1)(a+2)+1/(a+2)(a+3)+...+1/(a+2010)(a+2011)
【1】a+a=a×a a= [ ]【2】a×a=a÷a a=[ ]【3】a×a=a-a a=[ ] [4]a-a=a+a a=[ ]
化简(a+ 3)(a-3) (a-5)(a+7)-2a(a-1)
化简2a(a·a-3a-1)a乘a
(通分) a/a^a^a+3a+2 ,a/a^a+2a+1 ,-1/3a+6
(a-a/a+1)/(a*a-2a)*(a+1)/(a*a+3a+2)要详细的计算说明!
