Whakaoti mō x
x=-\frac{y^{2}}{4}
Whakaoti mō y (complex solution)
y=-2i\sqrt{x}
y=2i\sqrt{x}
Whakaoti mō y

Graph
Tohaina
Kua tāruatia ki te papatopenga
-4x=y^{2}
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
\frac{-4x}{-4}=\frac{y^{2}}{-4}
Whakawehea ngā taha e rua ki te -4.
x=\frac{y^{2}}{-4}
Mā te whakawehe ki te -4 ka wetekia te whakareanga ki te -4.
x=-\frac{y^{2}}{4}
Whakawehe y^{2} ki te -4.
