Whakaoti i te x^2=3600

$$x ^ { 2 } = 3600$$

Whakaoti mō x

$$x=60$$

$$x=-60$$

Ngā Hipanga Whakamahi Rerekētanga o ngā Pūrua

Tangohia te 3600 mai i ngā taha e rua.

$$x^{2}-3600=0$$

Whakaarohia te x^{2}-3600. Tuhia anō te x^{2}-3600 hei x^{2}-60^{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).

$$\left(x-60\right)\left(x+60\right)=0$$

Hei kimi otinga whārite, me whakaoti te x-60=0 me te x+60=0.

$$x=60 x=-60$$

Ngā Upane mā te Kimi Pūtakerua

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

$$x=60 x=-60$$

Ngā Upane e Whakamahi ana i te Tikanga Tātai Pūrua

Tangohia te 3600 mai i ngā taha e rua.

$$x^{2}-3600=0$$

Kei te āhua arowhānui tēnei whārite: ax^{2}+bx+c=0. Me whakakapi 1 mō a, 0 mō b, me -3600 mō c i te tikanga tātai pūrua, \frac{-b±\sqrt{b^{2}-4ac}}{2a}.

$$x=\frac{0±\sqrt{0^{2}-4\left(-3600\right)}}{2}$$

Pūrua 0.

$$x=\frac{0±\sqrt{-4\left(-3600\right)}}{2}$$

Whakareatia -4 ki te -3600.

$$x=\frac{0±\sqrt{14400}}{2}$$

Tuhia te pūtakerua o te 14400.

$$x=\frac{0±120}{2}$$

Nā, me whakaoti te whārite x=\frac{0±120}{2} ina he tāpiri te ±. Whakawehe 120 ki te 2.

$$x=60$$

Nā, me whakaoti te whārite x=\frac{0±120}{2} ina he tango te ±. Whakawehe -120 ki te 2.

$$x=-60$$

Kua oti te whārite te whakatau.

$$x=60 x=-60$$
