10x^{3}-3x+7
Whakarea ka paheko i ngā kīanga tau ōrite.
\left(x+1\right)\left(10x^{2}-10x+7\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 7, ā, ka wehea e q te whakarea arahanga 10. Ko tetahi pūtake pērā ko -1. Tauwehea te pūrau mā te whakawehe mā te x+1. Kāore te pūrau 10x^{2}-10x+7 i whakatauwehea i te mea kāhore ōna pūtake whakahau.
10x^{3}-3x+7
Whakareatia te 2 ki te 5, ka 10.
