Dear Artur, 
try this:

Table[Simplify@Factor@Numerator[(x^n - 1)/(x - 1)], {n, 1, 10}]


{1, -1 + x^2, -1 + x^3, -1 + x^4, -1 + x^5, -1 + x^6, -1 + x^7, -1 + 
  x^8, -1 + x^9, -1 + x^10}

Have fun, Alexei



Dear Mathematica Gurus.
Who know how force simplification of polynomials (x^n - 1)/(x - 1)] by 
Mathematica
Table[FullSimplify[(x^n - 1)/(x - 1)], {n, 1, 10}]
Above eliminate denominator only in first 5 n
Any idea ?
Best wishes
Artur
