Whakaoti i te x^2-4y-5=0

$$x ^ { 2 } - 4 y - 5 = 0$$

Whakaoti mō y

$$y=\frac{x^{2}-5}{4}$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Tangohia te x^{2} mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.

$$-4y-5=-x^{2}$$

Me tāpiri te 5 ki ngā taha e rua.

$$-4y=-x^{2}+5$$

He hanga arowhānui tō te whārite.

$$-4y=5-x^{2}$$

Whakawehea ngā taha e rua ki te -4.

$$\frac{-4y}{-4}=\frac{5-x^{2}}{-4}$$

Mā te whakawehe ki te -4 ka wetekia te whakareanga ki te -4.

$$y=\frac{5-x^{2}}{-4}$$

Whakawehe -x^{2}+5 ki te -4.

$$y=\frac{x^{2}-5}{4}$$

Whakaoti mō x (complex solution)

$$x=-\sqrt{4y+5}$$

$$x=\sqrt{4y+5}$$

Whakaoti mō x

$$x=\sqrt{4y+5}$$

$$x=-\sqrt{4y+5}\text{, }y\geq -\frac{5}{4}$$
