Question

( frac{x^{4}+x^{2}+1-x^{2} timesleft(x^{2}-x+1right)-2 xleft(x^{2}-x+1right)-left(x^{2}-x+1right)}{x^{2}-x+1} )
( frac{x^{4}+x^{2}+1-x^{4}+x^{3}-x^{2}-2 x^{3}+2 x^{2}-2 x-left(x^{2}-x+1right)}{x^{2}-x+1} )
( frac{1+x^{3}-2 x^{3}+2 x^{2}-2 x-x^{2}+x-1}{x^{2}-x+1} )
( frac{-x^{3}+x^{2}-x}{x^{2}-x+1} )
( frac{-x timesleft(x^{2}-x+1right)}{x^{2}-x+1} )
