Tauwehea te x.
\left(x-7\right)\left(-x^{2}-7x-49\right)
Whakaarohia te 343-x^{3}. 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 343, 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.
x\left(x-7\right)\left(-x^{2}-7x-49\right)
Me tuhi anō te kīanga whakatauwehe katoa. Kāore te pūrau -x^{2}-7x-49 i whakatauwehea i te mea kāhore ōna pūtake whakahau.
