Whakaoti mō y
y=\frac{x^{2}}{2}-\frac{15}{4}
Whakaoti mō x (complex solution)
x=-\frac{\sqrt{8y+30}}{2}
x=\frac{\sqrt{8y+30}}{2}
Whakaoti mō x
x=\frac{\sqrt{8y+30}}{2}
x=-\frac{\sqrt{8y+30}}{2}\text{, }y\geq -\frac{15}{4}
Graph
Tohaina
Kua tāruatia ki te papatopenga
-4y=15-2x^{2}
Tangohia te 2x^{2} mai i ngā taha e rua.
\frac{-4y}{-4}=\frac{15-2x^{2}}{-4}
Whakawehea ngā taha e rua ki te -4.
y=\frac{15-2x^{2}}{-4}
Mā te whakawehe ki te -4 ka wetekia te whakareanga ki te -4.
y=\frac{x^{2}}{2}-\frac{15}{4}
Whakawehe 15-2x^{2} ki te -4.
