\left(x+1\right)\left(-x^{2}+5x-5\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 -5, ā, ka wehea e q te whakarea arahanga -1. Ko tetahi pūtake pērā ko -1. Tauwehea te pūrau mā te whakawehe mā te x+1. Kāore te pūrau -x^{2}+5x-5 i whakatauwehea i te mea kāhore ōna pūtake whakahau.
