Numerator is divisible by denominator .
On dividing numerator by denominator the it is reduced to x2 -x +1
differentiating this we get 2x-1 as answer
SREEKANTH
on dividing numerator with denominator:(x^4+x^2+1)/(x^2+x+1)=
=((x^2+x+1)(x^2-x+1)+1)/(x^2+x+1)
=(x^2-x+1)+1/(x^2+x+1)
on differentiating the resulted equation we will get 2x-1+(-2x-1)/(x^2+x+1)^2
