化简:(a+1)(a-3)-(a-2)^2化简:(a+1)(a-3)-(a-2)^2化简:(a+1)(a-3)-(a-2)^2答:(a+1)(a-3)-(a-2)^2=(a^2-3a+a-3)-(a^
化简:(a+1)(a-3)-(a-2) ^2
化简:(a+1)(a-3)-(a-2) ^2
化简:(a+1)(a-3)-(a-2) ^2
答:
(a+1)(a-3)-(a-2) ^2
=(a^2-3a+a-3)-(a^2-4a+4)
=a^2-2a-3-a^2+4a-4
=2a-7
(通分) a/a^a^a+3a+2 ,a/a^a+2a+1 ,-1/3a+6
[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a(a+2)-(a-1)(a+1)
化简 3a-[5a-(a+2)+a]-1
化简:(a+1)(a-3)-(a-2) ^2
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)
化简:a(a*a-1)+2a*a(a+1)-3a(2a-5)拜托了各位
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)
化简1/a(a+10)+1/(a+1)(a+2)+...+1/(a+2009)(a+2010)
化简(a+ 3)(a-3) (a-5)(a+7)-2a(a-1)
