Whakaoti i te x^2-10=26

$$x ^ { 2 } - 10 = 26$$

Whakaoti mō x

$$x=6$$

$$x=-6$$

Ngā Hipanga Whakamahi Rerekētanga o ngā Pūrua

Tangohia te 26 mai i ngā taha e rua.

$$x^{2}-10-26=0$$

Tangohia te 26 i te -10, ka -36.

$$x^{2}-36=0$$

Whakaarohia te x^{2}-36. Tuhia anō te x^{2}-36 hei x^{2}-6^{2}. Ka taea te rerekētanga o ngā pūrua te whakatauwehe mā te ture: a^{2}-b^{2}=\left(a-b\right)\left(a+b\right).

$$\left(x-6\right)\left(x+6\right)=0$$

Hei kimi otinga whārite, me whakaoti te x-6=0 me te x+6=0.

$$x=6 x=-6$$

Ngā Upane mā te Kimi Pūtakerua

Me tāpiri te 10 ki ngā taha e rua.

$$x^{2}=26+10$$

Tāpirihia te 26 ki te 10, ka 36.

$$x^{2}=36$$

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

$$x=6 x=-6$$

Ngā Upane e Whakamahi ana i te Tikanga Tātai Pūrua

Tangohia te 26 mai i ngā taha e rua.

$$x^{2}-10-26=0$$

Tangohia te 26 i te -10, ka -36.

$$x^{2}-36=0$$

Kei te āhua arowhānui tēnei whārite: ax^{2}+bx+c=0. Me whakakapi 1 mō a, 0 mō b, me -36 mō c i te tikanga tātai pūrua, \frac{-b±\sqrt{b^{2}-4ac}}{2a}.

$$x=\frac{0±\sqrt{0^{2}-4\left(-36\right)}}{2}$$

Pūrua 0.

$$x=\frac{0±\sqrt{-4\left(-36\right)}}{2}$$

Whakareatia -4 ki te -36.

$$x=\frac{0±\sqrt{144}}{2}$$

Tuhia te pūtakerua o te 144.

$$x=\frac{0±12}{2}$$

Nā, me whakaoti te whārite x=\frac{0±12}{2} ina he tāpiri te ±. Whakawehe 12 ki te 2.

$$x=6$$

Nā, me whakaoti te whārite x=\frac{0±12}{2} ina he tango te ±. Whakawehe -12 ki te 2.

$$x=-6$$

Kua oti te whārite te whakatau.

$$x=6 x=-6$$
