I have to sequence 2*(n-1)*x^(2n), I have tried integrating and then finding the sum and then derivating the sum, and I allmost get the right answer.(adsbygoogle = window.adsbygoogle || []).push({});

But I think I am integrating wrong since I really dont know of the integrate when I have ^(2n), and not only n.

please help
