(通分) a/a^a^a+3a+2 ,a/a^a+2a+1 ,-1/3a+6
(通分) a/a^a^a+3a+2 ,a/a^a+2a+1 ,-1/3a+6

(通分) a/a^a^a+3a+2 ,a/a^a+2a+1 ,-1/3a+6
a/(a^2+3a+2)=a/(a+1)(a+2)=a(a+1)/(a+1)^2(a+2)
a/(a^2+2a+1)=a/(a+1)^2=a(a+2)/(a+1)^2(a+2)
-1/(3a+6)=-1/3(a+2) =-1/3×(a+1)^2/(a+1)^2(a+2)

通分后公分母为3*(a+2)(a+1)(a+1)
a/(a²+3a+2)分子为3a(a+1)
a/(a²+2a+1)分子为3a(a+2)
-1/(3a+6) 分子为-(a+2)(a+1)
