( iii ) :


\dfrac{x^{3} - 1}{x^{4}+x^{2}+1}


\dfrac{(x-1)(x^{2}+x+1)}{x^{4} -x^{3} + x^{2} +x^{3} - x^{2}+x+x^{2}-x+ 1}


\dfrac{(x-1)(x^{2}+x+1)}{x^{2}(x^{2}-x+1 ) + x(x^{2}-x+1) +(x^{2}-x+1)}


\dfrac{(x-1)(x^{2}+x+1)}{(x^{2}-x+1)(x^{2}+x+1)}


\dfrac{x-1}{x^{2}-x+1}



Answer : \dfrac{x-1}{x^{2} - x+ 1 }




( iv ) :


\dfrac{x^{8}-y^{8}}{(x-y)(x^{4}+y^{4})}


\dfrac{(x^{4}-y^{4})(x^{4}+y^{4})}{(x-y)(x^{4}+y^{4})}


\dfrac{(x^{2}-y^{2})(x^{2}+y^{2})}{x-y}


\dfrac{(x-y)(x+y)(x^{2}+y^{2})}{x-y}


( x + y )( x^2 + y^2 )



Answer :  ( x + y )( x^2 + y^2 )
