Whakaoti i te (x-65)^2=2125

$$( x - 65 ) ^ { 2 } = 2125$$

Whakaoti mō x

$$x=5\sqrt{85}+65\approx 111.097722286$$

$$x=65-5\sqrt{85}\approx 18.902277714$$

Ngā Upane mā te Kimi Pūtakerua

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

$$x-65=5\sqrt{85} x-65=-5\sqrt{85}$$

Me tāpiri 65 ki ngā taha e rua o te whārite.

$$x-65-\left(-65\right)=5\sqrt{85}-\left(-65\right) x-65-\left(-65\right)=-5\sqrt{85}-\left(-65\right)$$

Mā te tango i te -65 i a ia ake anō ka toe ko te 0.

$$x=5\sqrt{85}-\left(-65\right) x=-5\sqrt{85}-\left(-65\right)$$

Tango -65 mai i 5\sqrt{85}.

$$x=5\sqrt{85}+65$$

Tango -65 mai i -5\sqrt{85}.

$$x=65-5\sqrt{85}$$

Kua oti te whārite te whakatau.

$$x=5\sqrt{85}+65 x=65-5\sqrt{85}$$
