Whakaoti i te xdiv4x=16

$$x \div 4x=16$$

Whakaoti mō x

$$x=8$$

$$x=-8$$

Ngā Upane mā te Kimi Pūtakerua

Whakareatia ngā taha e rua o te whārite ki te 4.

$$xx=64$$

Whakareatia te x ki te x, ka x^{2}.

$$x^{2}=64$$

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

$$x=8 x=-8$$

Ngā Upane e Whakamahi ana i te Tikanga Tātai Pūrua

Whakareatia ngā taha e rua o te whārite ki te 4.

$$xx=64$$

Whakareatia te x ki te x, ka x^{2}.

$$x^{2}=64$$

Tangohia te 64 mai i ngā taha e rua.

$$x^{2}-64=0$$

Kei te āhua arowhānui tēnei whārite: ax^{2}+bx+c=0. Me whakakapi 1 mō a, 0 mō b, me -64 mō c i te tikanga tātai pūrua, \frac{-b±\sqrt{b^{2}-4ac}}{2a}.

$$x=\frac{0±\sqrt{0^{2}-4\left(-64\right)}}{2}$$

Pūrua 0.

$$x=\frac{0±\sqrt{-4\left(-64\right)}}{2}$$

Whakareatia -4 ki te -64.

$$x=\frac{0±\sqrt{256}}{2}$$

Tuhia te pūtakerua o te 256.

$$x=\frac{0±16}{2}$$

Nā, me whakaoti te whārite x=\frac{0±16}{2} ina he tāpiri te ±. Whakawehe 16 ki te 2.

$$x=8$$

Nā, me whakaoti te whārite x=\frac{0±16}{2} ina he tango te ±. Whakawehe -16 ki te 2.

$$x=-8$$

Kua oti te whārite te whakatau.

$$x=8 x=-8$$
