x^{4}-4x^{2}+3=0
Kia tauwehea ai te kīanga, me whakaoti te whārite ina ōrite ki te 0.
±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 3, 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^{3}+x^{2}-3x-3=0
Mā te whakatakotoranga Tauwehe, he tauwehe te x-k o te pūrau mō ia pūtake k. Whakawehea te x^{4}-4x^{2}+3 ki te x-1, kia riro ko x^{3}+x^{2}-3x-3. Kia tauwehea ai te otinga, me whakaoti te whārite ina ōrite ki te 0.
±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 -3, 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}-3=0
Mā te whakatakotoranga Tauwehe, he tauwehe te x-k o te pūrau mō ia pūtake k. Whakawehea te x^{3}+x^{2}-3x-3 ki te x+1, kia riro ko x^{2}-3. Kia tauwehea ai te otinga, me whakaoti te whārite ina ōrite ki te 0.
x=\frac{0±\sqrt{0^{2}-4\times 1\left(-3\right)}}{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 0 mō te b, me te -3 mō te c i te ture pūrua.
x=\frac{0±2\sqrt{3}}{2}
Mahia ngā tātaitai.
x=-\sqrt{3} x=\sqrt{3}
Whakaotia te whārite x^{2}-3=0 ina he tōrunga te ±, ina he tōraro te ±.
\left(x-1\right)\left(x+1\right)\left(x^{2}-3\right)
Me tuhi anō te kīanga whakatauwehe mā ngā pūtake i riro. Kāore te pūrau x^{2}-3 i whakatauwehea i te mea kāhore ōna pūtake whakahau.
