Whakaoti i te -3^2=a^2

$$- 3 ^ { 2 } = a ^ { 2 }$$

Whakaoti mō a

$$a=3i$$

$$a=-3i$$

Ngā Upane mā te Kimi Pūtakerua

Tātaihia te 3 mā te pū o 2, kia riro ko 9.

$$-9=a^{2}$$

Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.

$$a^{2}=-9$$

Kua oti te whārite te whakatau.

$$a=3i a=-3i$$

Ngā Upane e Whakamahi ana i te Tikanga Tātai Pūrua

Tātaihia te 3 mā te pū o 2, kia riro ko 9.

$$-9=a^{2}$$

Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.

$$a^{2}=-9$$

Me tāpiri te 9 ki ngā taha e rua.

$$a^{2}+9=0$$

Kei te āhua arowhānui tēnei whārite: ax^{2}+bx+c=0. Me whakakapi 1 mō a, 0 mō b, me 9 mō c i te tikanga tātai pūrua, \frac{-b±\sqrt{b^{2}-4ac}}{2a}.

$$a=\frac{0±\sqrt{0^{2}-4\times 9}}{2}$$

Pūrua 0.

$$a=\frac{0±\sqrt{-4\times 9}}{2}$$

Whakareatia -4 ki te 9.

$$a=\frac{0±\sqrt{-36}}{2}$$

Tuhia te pūtakerua o te -36.

$$a=\frac{0±6i}{2}$$

Nā, me whakaoti te whārite a=\frac{0±6i}{2} ina he tāpiri te ±.

$$a=3i$$

Nā, me whakaoti te whārite a=\frac{0±6i}{2} ina he tango te ±.

$$a=-3i$$

Kua oti te whārite te whakatau.

$$a=3i a=-3i$$
