Whakaoti i te left(x-3right)^2=5

$${ \left(x-3 \right) }^{ 2 } =5$$

Whakaoti mō x

$$x=\sqrt{5}+3\approx 5.236067977$$

$$x=3-\sqrt{5}\approx 0.763932023$$

Ngā Upane mā te Kimi Pūtakerua

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

$$x-3=\sqrt{5} x-3=-\sqrt{5}$$

Me tāpiri 3 ki ngā taha e rua o te whārite.

$$x-3-\left(-3\right)=\sqrt{5}-\left(-3\right) x-3-\left(-3\right)=-\sqrt{5}-\left(-3\right)$$

Mā te tango i te -3 i a ia ake anō ka toe ko te 0.

$$x=\sqrt{5}-\left(-3\right) x=-\sqrt{5}-\left(-3\right)$$

Tango -3 mai i \sqrt{5}.

$$x=\sqrt{5}+3$$

Tango -3 mai i -\sqrt{5}.

$$x=3-\sqrt{5}$$

Kua oti te whārite te whakatau.

$$x=\sqrt{5}+3 x=3-\sqrt{5}$$
