Kua tāruatia ki te papatopenga
2xy=-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{2xy}{2x}=-\frac{x^{2}}{2x}
Whakawehea ngā taha e rua ki te 2x.
y=-\frac{x^{2}}{2x}
Mā te whakawehe ki te 2x ka wetekia te whakareanga ki te 2x.
y=-\frac{x}{2}
Whakawehe -x^{2} ki te 2x.
