计算:(1)(a/a^2-1)+(3a+1/a^2-1)+(2a+3/1-a^2)计算:(1)(a/a^2-1)+(3a+1/a^2-1)+(2a+3/1-a^2)计算:(1)(a/a^2-1)+(3
计算:(1)(a/a^2-1)+(3a+1/a^2-1)+(2a+3/1-a^2)
计算:(1)(a/a^2-1)+(3a+1/a^2-1)+(2a+3/1-a^2)
计算:(1)(a/a^2-1)+(3a+1/a^2-1)+(2a+3/1-a^2)
(a/a^2-1)+(3a+1/a^2-1)+(2a+3/1-a^2)
=(a+3a+1-2a-3)/(a^2-1)
=2(a-1)/(a^2-1)
=2(a-1)/(a-1)(a+1)
=2/(a+1)
(a+1)(a+2)(a-3)计算
计算(a^2+a+1)/(a+1)-(a^2-3a+1)/(a-3)
计算:(2a+3)(a²+a-1)
计算(a+1)(a+2)(a+3)(a-6)
计算,(a+3)(a-1)+a(a-2)
(a+3)(a-1)+a(a+2)化简计算,
计算:(a+3)(a—1)+a(a—2)
计算(a+3)(a-1)-a(a-2)
(a-a/a+1)/(a*a-2a)*(a+1)/(a*a+3a+2)要详细的计算说明!
计算a+a-2分之3-1

计算(-2a)×(1/4a^3)
计算 a^2/1+a+1-a
计算:[a-(1/a)]/a^2-2a+1/a
计算(a-3)(1-a)/a^2-2a+1乘a-1/3-a
计算2a(a-3)^1-6a^2(3-a)-8a(a-3)
分式计算(a+1/a^2+3a+2)+(a+3/a^2+7a+12)
计算:-a³(a²-a-1)+a(-a³+2a).
