33t^{2}+1826t-75779=0
Whakakapia te t mō te t^{2}.
t=\frac{-1826±\sqrt{1826^{2}-4\times 33\left(-75779\right)}}{2\times 33}
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 33 mō te a, te 1826 mō te b, me te -75779 mō te c i te ture pūrua.
t=\frac{-1826±3652}{66}
Mahia ngā tātaitai.
t=\frac{83}{3} t=-83
Whakaotia te whārite t=\frac{-1826±3652}{66} ina he tōrunga te ±, ina he tōraro te ±.
t=\frac{\sqrt{249}}{3} t=-\frac{\sqrt{249}}{3}
I te mea ko t=t^{2}, ka riro ngā otinga mā te arotake i te t=±\sqrt{t} mō t tōrunga.
