x^{2}+24x-23=0
Ko ngā whārite katoa o te āhua ax^{2}+bx+c=0 ka taea te whakaoti mā te whakamahi i te tikanga tātai pūrua: \frac{-b±\sqrt{b^{2}-4ac}}{2a}. E rua ngā otinga ka puta i te tikanga tātai pūrua, ko tētahi ina he tāpiri a ±, ā, ko tētahi ina he tango.
x=\frac{-24±\sqrt{24^{2}-4\left(-23\right)}}{2}
Kei te āhua arowhānui tēnei whārite: ax^{2}+bx+c=0. Me whakakapi 1 mō a, 24 mō b, me -23 mō c i te tikanga tātai pūrua, \frac{-b±\sqrt{b^{2}-4ac}}{2a}.

x=\frac{2\sqrt{167}-24}{2}
Nā, me whakaoti te whārite x=\frac{-24±2\sqrt{167}}{2} ina he tāpiri te ±. Tāpiri -24 ki te 2\sqrt{167}.
x=\sqrt{167}-12
Whakawehe -24+2\sqrt{167} ki te 2.
x=\frac{-2\sqrt{167}-24}{2}
Nā, me whakaoti te whārite x=\frac{-24±2\sqrt{167}}{2} ina he tango te ±. Tango 2\sqrt{167} mai i -24.

x^{2}+24x-23=0
Ko ngā whārite pūrua pēnei i tēnei nā ka taea te whakaoti mā te whakaoti i te pūrua. Hei whakaoti i te pūrua, ko te whārite me mātua tuhi ki te āhua x^{2}+bx=c.
x^{2}+24x-23-\left(-23\right)=-\left(-23\right)
Me tāpiri 23 ki ngā taha e rua o te whārite.
x^{2}+24x=-\left(-23\right)
Mā te tango i te -23 i a ia ake anō ka toe ko te 0.
x^{2}+24x=23

x^{2}+24x+12^{2}=23+12^{2}
Whakawehea te 24, te tau whakarea o te kīanga tau x, ki te 2 kia riro ai te 12. Nā, tāpiria te pūrua o te 12 ki ngā taha e rua o te whārite. Mā konei e pūrua tika tonu ai te taha mauī o te whārite.
x^{2}+24x+144=23+144
Pūrua 12.
x^{2}+24x+144=167

\left(x+12\right)^{2}=167
Tauwehea x^{2}+24x+144. Ko te tikanga pūnoa, ina ko x^{2}+bx+c he pūrua tika pūrua tika pū, ka taea taua mea te tauwehea i ngā wā katoa hei \left(x+\frac{b}{2}\right)^{2}.
\sqrt{\left(x+12\right)^{2}}=\sqrt{167}
Tuhia te pūtakerua o ngā taha e rua o te whārite.
x+12=\sqrt{167} x+12=-\sqrt{167}
Whakarūnātia.
