Whakaoti i te 7.5=5t^2

$$7.5 = 5 t ^ { 2 }$$

Whakaoti mō t

$$t = \frac{\sqrt{6}}{2} \approx 1.224744871$$

$$t = -\frac{\sqrt{6}}{2} \approx -1.224744871$$

Ngā Upane mā te Kimi Pūtakerua

Whakawehea ngā taha e rua ki te 5.

$$\frac{7.5}{5}=t^{2}$$

Whakarohaina te \frac{7.5}{5} mā te whakarea i te taurunga me te tauraro ki te 10.

$$\frac{75}{50}=t^{2}$$

Whakahekea te hautanga \frac{75}{50} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 25.

$$\frac{3}{2}=t^{2}$$

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

$$t^{2}=\frac{3}{2}$$

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

$$t=\frac{\sqrt{6}}{2} t=-\frac{\sqrt{6}}{2}$$

Ngā Upane e Whakamahi ana i te Tikanga Tātai Pūrua

Whakawehea ngā taha e rua ki te 5.

$$\frac{7.5}{5}=t^{2}$$

Whakarohaina te \frac{7.5}{5} mā te whakarea i te taurunga me te tauraro ki te 10.

$$\frac{75}{50}=t^{2}$$

Whakahekea te hautanga \frac{75}{50} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 25.

$$\frac{3}{2}=t^{2}$$

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

$$t^{2}=\frac{3}{2}$$

Tangohia te \frac{3}{2} mai i ngā taha e rua.

$$t^{2}-\frac{3}{2}=0$$

Kei te āhua arowhānui tēnei whārite: ax^{2}+bx+c=0. Me whakakapi 1 mō a, 0 mō b, me -\frac{3}{2} mō c i te tikanga tātai pūrua, \frac{-b±\sqrt{b^{2}-4ac}}{2a}.

$$t=\frac{0±\sqrt{0^{2}-4\left(-\frac{3}{2}\right)}}{2}$$

Pūrua 0.

$$t=\frac{0±\sqrt{-4\left(-\frac{3}{2}\right)}}{2}$$

Whakareatia -4 ki te -\frac{3}{2}.

$$t=\frac{0±\sqrt{6}}{2}$$

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

$$t=\frac{\sqrt{6}}{2}$$

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

$$t=-\frac{\sqrt{6}}{2}$$

Kua oti te whārite te whakatau.

$$t=\frac{\sqrt{6}}{2} t=-\frac{\sqrt{6}}{2}$$
