Kua tāruatia ki te papatopenga
x^{2}=-12+10
Me tāpiri te 10 ki ngā taha e rua.
x^{2}=-2
Tāpirihia te -12 ki te 10, ka -2.
x=\sqrt{2}i x=-\sqrt{2}i
Kua oti te whārite te whakatau.
x^{2}-10+12=0
Me tāpiri te 12 ki ngā taha e rua.
x^{2}+2=0
Tāpirihia te -10 ki te 12, ka 2.
x=\frac{0±\sqrt{0^{2}-4\times 2}}{2}
Kei te āhua arowhānui tēnei whārite: ax^{2}+bx+c=0. Me whakakapi 1 mō a, 0 mō b, me 2 mō c i te tikanga tātai pūrua, \frac{-b±\sqrt{b^{2}-4ac}}{2a}.
x=\frac{0±\sqrt{-4\times 2}}{2}
Pūrua 0.
x=\frac{0±\sqrt{-8}}{2}
Whakareatia -4 ki te 2.
x=\frac{0±2\sqrt{2}i}{2}
Tuhia te pūtakerua o te -8.
x=\sqrt{2}i
Nā, me whakaoti te whārite x=\frac{0±2\sqrt{2}i}{2} ina he tāpiri te ±.
x=-\sqrt{2}i
Nā, me whakaoti te whārite x=\frac{0±2\sqrt{2}i}{2} ina he tango te ±.
x=\sqrt{2}i x=-\sqrt{2}i
Kua oti te whārite te whakatau.
