±\frac{5}{3},±5,±\frac{1}{3},±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 -5, ā, ka wehea e q te whakarea arahanga 3. 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.
3x^{2}+5x+5=0
Mā te whakatakotoranga Tauwehe, he tauwehe te x-k o te pūrau mō ia pūtake k. Whakawehea te 3x^{3}+2x^{2}-5 ki te x-1, kia riro ko 3x^{2}+5x+5. Whakaotihia te whārite ina ōrite te hua ki te 0.
x=\frac{-5±\sqrt{5^{2}-4\times 3\times 5}}{2\times 3}
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 3 mō te a, te 5 mō te b, me te 5 mō te c i te ture pūrua.
x=\frac{-5±\sqrt{-35}}{6}
Mahia ngā tātaitai.
x=\frac{-\sqrt{35}i-5}{6} x=\frac{-5+\sqrt{35}i}{6}
Whakaotia te whārite 3x^{2}+5x+5=0 ina he tōrunga te ±, ina he tōraro te ±.
x=1 x=\frac{-\sqrt{35}i-5}{6} x=\frac{-5+\sqrt{35}i}{6}
Rārangitia ngā otinga katoa i kitea.

3x^{2}+5x+5=0
Mā te whakatakotoranga Tauwehe, he tauwehe te x-k o te pūrau mō ia pūtake k. Whakawehea te 3x^{3}+2x^{2}-5 ki te x-1, kia riro ko 3x^{2}+5x+5. Whakaotihia te whārite ina ōrite te hua ki te 0.
x=\frac{-5±\sqrt{5^{2}-4\times 3\times 5}}{2\times 3}
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 3 mō te a, te 5 mō te b, me te 5 mō te c i te ture pūrua.
x=\frac{-5±\sqrt{-35}}{6}
Mahia ngā tātaitai.
x\in \emptyset
Tā te mea e kore te pūrua o tētahi tau tōraro e tautohutia ki te āpure tūturu, kāhore he rongoā.
x=1
Rārangitia ngā otinga katoa i kitea.
