Kua tāruatia ki te papatopenga
m^{2}+6m+13=61+m^{2}
Tāpirihia te 16 ki te 45, ka 61.
m^{2}+6m+13-m^{2}=61
Tangohia te m^{2} mai i ngā taha e rua.
6m+13=61
Pahekotia te m^{2} me -m^{2}, ka 0.
6m=61-13
Tangohia te 13 mai i ngā taha e rua.
6m=48
Tangohia te 13 i te 61, ka 48.
m=\frac{48}{6}
Whakawehea ngā taha e rua ki te 6.
m=8
Whakawehea te 48 ki te 6, kia riro ko 8.
