x^{3}-3+2=0
Me tāpiri te 2 ki ngā taha e rua.
x^{3}-1=0
Tāpirihia te -3 ki te 2, ka -1.
±1
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 -1, ā, ka wehea e q te whakarea arahanga 1. Whakarārangitia ngā kaitono katoa \frac{p}{q}.
x=1
Kimihia tētahi pūtake pērā mā te whakamātau i ngā uara tau tōpū katoa, e tīmata ana i te mea iti rawa mā te uara pū. Mēnā kāore he pūtake tau tōpū e kitea, whakamātauria ngā hautanga.
x^{2}+x+1=0
Mā te whakatakotoranga Tauwehe, he tauwehe te x-k o te pūrau mō ia pūtake k. Whakawehea te x^{3}-1 ki te x-1, kia riro ko x^{2}+x+1. Whakaotihia te whārite ina ōrite te hua ki te 0.
x=\frac{-1±\sqrt{1^{2}-4\times 1\times 1}}{2}
Ka taea ngā whārite katoa o te momo ax^{2}+bx+c=0 te whakaoti mā te ture pūrua: \frac{-b±\sqrt{b^{2}-4ac}}{2a}. Whakakapia te 1 mō te a, te 1 mō te b, me te 1 mō te c i te ture pūrua.
x=\frac{-1±\sqrt{-3}}{2}
Mahia ngā tātaitai.
x=\frac{-\sqrt{3}i-1}{2} x=\frac{-1+\sqrt{3}i}{2}
Whakaotia te whārite x^{2}+x+1=0 ina he tōrunga te ±, ina he tōraro te ±.
x=1 x=\frac{-\sqrt{3}i-1}{2} x=\frac{-1+\sqrt{3}i}{2}
Rārangitia ngā otinga katoa i kitea.
