(a+2)(a-1)化简
(a+2)(a-1)化简
(a+2)(a-1)化简
(a+2)(a-1)
=a²-a+2a-2
=a²+a-2
=(a+2)*a-(a+2)
=a*a+2a-a-2
=a*a+a-2
化简a(a+2)-(a-1)(a+1)
化简1/a(a+10)+1/(a+1)(a+2)+...+1/(a+2009)(a+2010)
(通分) a/a^a^a+3a+2 ,a/a^a+2a+1 ,-1/3a+6
化简:(a-a/a+1)÷(a²-2a)/(a²-4)×1/(a+2)
化简:(2a+1/a²-1)*a²-2a+1/a²-a-(1/a+1)
化简[a^2+a/a^2-1+(a^2-a分之根号下a^2-2a+1)
(2+1/a-1-1/a+1)÷(a-a/1-a²)化简
化简(a + (1/a))*(1-a^2)/(1+2a+a^2)
化简a分之a方-1+a分之a+1的结果是( )A.a+a^2 B.a-1 C.a+1 D.1
化简:(2a/a-1+a/1-a)除以a
化简:(a+1)(a-3)-(a-2) ^2
(-a)^2n+1 +a*(-a)^2n 化简?
化简(a^3-a)(a^2+1)等于多少?
化简:3a-[5a-(2a-1)]=
化简:(a/a²)-(2a+1/3-a)+(2-a/9-a²)sorry,(a/a²-2a)+(1/3-a)/(2-a/9-a²)
(a+2)(a-1)化简
化简2(a+1)-a
化简:1-(a-1/1-a)²÷(a²-a+1)/(a²-2a+1)
