Whakaoti mō y
y=7-2x^{2}
Whakaoti mō x (complex solution)
x=-\frac{\sqrt{14-2y}}{2}
x=\frac{\sqrt{14-2y}}{2}
Whakaoti mō x
x=\frac{\sqrt{14-2y}}{2}
x=-\frac{\sqrt{14-2y}}{2}\text{, }y\leq 7

Kua tāruatia ki te papatopenga
y-7=-2x^{2}
Tangohia te 2x^{2} mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
y=-2x^{2}+7
Me tāpiri te 7 ki ngā taha e rua.
