Can someone please look at my drawing and tell me if I separated the integral correctly? Thanks!

The computer said I was wrong because x^4+2x^2+1 is a perfect square of (x^2+1)^2...and they got a different answer...if they are right, can you tell me why I am wrong? Isn't it okay to integrate without completely factoring it down?
