Whakaoti i te 39=c^2-10c*(074)

$$39 = c ^ { 2 } - 10 c \times ( 074 )$$

Whakaoti mō c

$$c=\sqrt{39}\approx 6.244997998$$

$$c=-\sqrt{39}\approx -6.244997998$$

Ngā Upane mā te Kimi Pūtakerua

Whakareatia te 10 ki te 0, ka 0.

$$39=c^{2}-0c\times 74$$

Whakareatia te 0 ki te 74, ka 0.

$$39=c^{2}-0c$$

Ko te tau i whakarea ki te kore ka hua ko te kore.

$$39=c^{2}-0$$

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

$$c^{2}-0=39$$

Me tāpiri te 0 ki ngā taha e rua.

$$c^{2}=39+0$$

Tāpirihia te 39 ki te 0, ka 39.

$$c^{2}=39$$

Tuhia te pūtakerua o ngā taha e rua o te whārite.

$$c=\sqrt{39} c=-\sqrt{39}$$

Ngā Upane e Whakamahi ana i te Tikanga Tātai Pūrua

Whakareatia te 10 ki te 0, ka 0.

$$39=c^{2}-0c\times 74$$

Whakareatia te 0 ki te 74, ka 0.

$$39=c^{2}-0c$$

Ko te tau i whakarea ki te kore ka hua ko te kore.

$$39=c^{2}-0$$

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

$$c^{2}-0=39$$

Tangohia te 39 mai i ngā taha e rua.

$$c^{2}-0-39=0$$

Whakaraupapatia anō ngā kīanga tau.

$$c^{2}-39=0$$

Kei te āhua arowhānui tēnei whārite: ax^{2}+bx+c=0. Me whakakapi 1 mō a, 0 mō b, me -39 mō c i te tikanga tātai pūrua, \frac{-b±\sqrt{b^{2}-4ac}}{2a}.

$$c=\frac{0±\sqrt{0^{2}-4\left(-39\right)}}{2}$$

Pūrua 0.

$$c=\frac{0±\sqrt{-4\left(-39\right)}}{2}$$

Whakareatia -4 ki te -39.

$$c=\frac{0±\sqrt{156}}{2}$$

Tuhia te pūtakerua o te 156.

$$c=\frac{0±2\sqrt{39}}{2}$$

Nā, me whakaoti te whārite c=\frac{0±2\sqrt{39}}{2} ina he tāpiri te ±.

$$c=\sqrt{39}$$

Nā, me whakaoti te whārite c=\frac{0±2\sqrt{39}}{2} ina he tango te ±.

$$c=-\sqrt{39}$$

Kua oti te whārite te whakatau.

$$c=\sqrt{39} c=-\sqrt{39}$$
