Okay the question ask to integrate the above expression so the first thing i did was to equate u=x

^{2}so u'=2x and got this [tex]\frac{1}{2}[/tex][tex]\int\frac{1}{u^2+u+1}[/tex]du. I then proceed to use integration by parts which i find that this method is too long and messy so i was wondering is there a better to do this
