Kua tāruatia ki te papatopenga
x=4i x=-4i
Kua oti te whārite te whakatau.
x^{2}+16=0
Me tāpiri te 16 ki ngā taha e rua.
x=\frac{0±\sqrt{0^{2}-4\times 16}}{2}
Kei te āhua arowhānui tēnei whārite: ax^{2}+bx+c=0. Me whakakapi 1 mō a, 0 mō b, me 16 mō c i te tikanga tātai pūrua, \frac{-b±\sqrt{b^{2}-4ac}}{2a}.
x=\frac{0±\sqrt{-4\times 16}}{2}
Pūrua 0.
x=\frac{0±\sqrt{-64}}{2}
Whakareatia -4 ki te 16.
x=\frac{0±8i}{2}
Tuhia te pūtakerua o te -64.
x=4i
Nā, me whakaoti te whārite x=\frac{0±8i}{2} ina he tāpiri te ±.
x=-4i
Nā, me whakaoti te whārite x=\frac{0±8i}{2} ina he tango te ±.
x=4i x=-4i
Kua oti te whārite te whakatau.
