Whakarea ka paheko i ngā kīanga tau ōrite.
\left(x-7\right)\left(x^{2}+7x+48\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 -336, ā, ka wehea e q te whakarea arahanga 1. Ko tetahi pūtake pērā ko 7. Tauwehea te pūrau mā te whakawehe mā te x-7. Kāore te pūrau x^{2}+7x+48 i whakatauwehea i te mea kāhore ōna pūtake whakahau.
x^{3}-336-x
Tāpirihia te -343 ki te 7, ka -336.
