Whakaoti mō y
y=-\frac{x^{2}}{2}+\frac{25}{4}
Whakaoti mō x (complex solution)
x=-\frac{\sqrt{50-8y}}{2}
x=\frac{\sqrt{50-8y}}{2}
Whakaoti mō x
x=\frac{\sqrt{50-8y}}{2}
x=-\frac{\sqrt{50-8y}}{2}\text{, }y\leq \frac{25}{4}
Graph
Tohaina
Kua tāruatia ki te papatopenga
4y=25-2x^{2}
Tangohia te 2x^{2} mai i ngā taha e rua.
\frac{4y}{4}=\frac{25-2x^{2}}{4}
Whakawehea ngā taha e rua ki te 4.
y=\frac{25-2x^{2}}{4}
Mā te whakawehe ki te 4 ka wetekia te whakareanga ki te 4.
y=-\frac{x^{2}}{2}+\frac{25}{4}
Whakawehe 25-2x^{2} ki te 4.
