Whakaoti mō y
y=-\frac{x^{2}}{2}
Whakaoti mō x (complex solution)
x=-i\sqrt{2y}
x=i\sqrt{2y}
Whakaoti mō x
x=\sqrt{-2y}
x=-\sqrt{-2y}\text{, }y\leq 0
Graph
Tohaina
Kua tāruatia ki te papatopenga
2y=-x^{2}
Tangohia te x^{2} mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
\frac{2y}{2}=-\frac{x^{2}}{2}
Whakawehea ngā taha e rua ki te 2.
y=-\frac{x^{2}}{2}
Mā te whakawehe ki te 2 ka wetekia te whakareanga ki te 2.
