Tohaina
Kua tāruatia ki te papatopenga
ix=\frac{282}{5}
Whakahekea te hautanga \frac{564}{10} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.
x=\frac{\frac{282}{5}}{i}
Whakawehea ngā taha e rua ki te i.
x=\frac{\frac{282}{5}i}{1i^{2}}
Me whakarea tahi te taurunga me te tauraro o \frac{\frac{282}{5}}{i} ki te wae pohewa i.
x=\frac{\frac{282}{5}i}{-1}
Hei tōna tikanga, ko te i^{2} ko -1. Tātaitia te tauraro.
x=-\frac{282}{5}i
Whakawehea te \frac{282}{5}i ki te -1, kia riro ko -\frac{282}{5}i.
