Whakaoti i te y^2=26

$$y ^ { 2 } = 26$$

Whakaoti mō y

$$y=\sqrt{26}\approx 5.099019514$$

$$y=-\sqrt{26}\approx -5.099019514$$

Ngā Upane mā te Kimi Pūtakerua

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

$$y=\sqrt{26} y=-\sqrt{26}$$

Ngā Upane e Whakamahi ana i te Tikanga Tātai Pūrua

Tangohia te 26 mai i ngā taha e rua.

$$y^{2}-26=0$$

Kei te āhua arowhānui tēnei whārite: ax^{2}+bx+c=0. Me whakakapi 1 mō a, 0 mō b, me -26 mō c i te tikanga tātai pūrua, \frac{-b±\sqrt{b^{2}-4ac}}{2a}.

$$y=\frac{0±\sqrt{0^{2}-4\left(-26\right)}}{2}$$

Pūrua 0.

$$y=\frac{0±\sqrt{-4\left(-26\right)}}{2}$$

Whakareatia -4 ki te -26.

$$y=\frac{0±\sqrt{104}}{2}$$

Tuhia te pūtakerua o te 104.

$$y=\frac{0±2\sqrt{26}}{2}$$

Nā, me whakaoti te whārite y=\frac{0±2\sqrt{26}}{2} ina he tāpiri te ±.

$$y=\sqrt{26}$$

Nā, me whakaoti te whārite y=\frac{0±2\sqrt{26}}{2} ina he tango te ±.

$$y=-\sqrt{26}$$

Kua oti te whārite te whakatau.

$$y=\sqrt{26} y=-\sqrt{26}$$
