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