Fixing, we may view this as a polynomial identity with respect to . Comparing the coefficients of, we see that, so for which, along with the additivity, implies that increases monotonously.
Pag-aayos, Maaari naming tingnan ito bilang isang polinomyal pagkakakilanlan na may paggalang sa . Ang paghahambing ng mga coefficients ng mga, Nakita namin na, Kaya para sa kung saan, kasama ang additivity, nagpapahiwatig na nadadagdagan monotonously.
