\left(x-2\right)\left(x^{2}+3x+1\right)
Tā te Rational Root Theorem, ko ngā pūtake whakahau katoa o tētahi pūrau kei te āhua o \frac{p}{q}, ina wehea e p te kīanga pūmau -2, ā, ka wehea e q te whakarea arahanga 1. Ko tetahi pūtake pērā ko 2. Tauwehea te pūrau mā te whakawehe mā te x-2. Kāore te pūrau x^{2}+3x+1 i whakatauwehea i te mea kāhore ōna pūtake whakahau.
