Whakaoti i te y=x^2-a

$$y = x ^ { 2 } - a$$

Whakaoti mō a

$$a=x^{2}-y$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.

$$x^{2}-a=y$$

Tangohia te x^{2} mai i ngā taha e rua.

$$-a=y-x^{2}$$

Whakawehea ngā taha e rua ki te -1.

$$\frac{-a}{-1}=\frac{y-x^{2}}{-1}$$

Mā te whakawehe ki te -1 ka wetekia te whakareanga ki te -1.

$$a=\frac{y-x^{2}}{-1}$$

Whakawehe y-x^{2} ki te -1.

$$a=x^{2}-y$$

Whakaoti mō x (complex solution)

$$x=-\sqrt{y+a}$$

$$x=\sqrt{y+a}$$

Whakaoti mō x

$$x=\sqrt{y+a}$$

$$x=-\sqrt{y+a}\text{, }y\geq -a$$
