化简(2a的2n+2次方+3a的2n+1次方)(a-5)/(a的2n次方-5a的2n-1次方)(2a+3)的结果为化简(2a的2n+2次方+3a的2n+1次方)(a-5)/(a的2n次方-5a的2n-

化简(2a的2n+2次方+3a的2n+1次方)(a-5)/(a的2n次方-5a的2n-1次方)(2a+3)的结果为
化简(2a的2n+2次方+3a的2n+1次方)(a-5)/(a的2n次方-5a的2n-1次方)(2a+3)的结果为

化简(2a的2n+2次方+3a的2n+1次方)(a-5)/(a的2n次方-5a的2n-1次方)(2a+3)的结果为
化简(2a的2n+2次方+3a的2n+1次方)(a-5)/(a的2n次方-5a的2n-1次方)(2a+3)
=a^(2n-1)(2a^3 + 3a^2)(a-5)/[a^(2n-1)(a-5)(2a+3)]
=(2a^3 + 3a^2)(a-5)/[(a-5)(2a+3)]
=a^2(2a + 3)(a-5)/[(a-5)(2a+3)]
=a^2
