Tohaina
Kua tāruatia ki te papatopenga
\frac{\sqrt{k-1}}{3}+m=n
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
\frac{\sqrt{k-1}}{3}=n-m
Tangohia te m mai i ngā taha e rua.
\sqrt{k-1}=3n-3m
Whakareatia ngā taha e rua o te whārite ki te 3.
k-1=9\left(n-m\right)^{2}
Pūruatia ngā taha e rua o te whārite.
k-1-\left(-1\right)=9\left(n-m\right)^{2}-\left(-1\right)
Me tāpiri 1 ki ngā taha e rua o te whārite.
k=9\left(n-m\right)^{2}-\left(-1\right)
Mā te tango i te -1 i a ia ake anō ka toe ko te 0.
k=9\left(n-m\right)^{2}+1
Tango -1 mai i 9\left(n-m\right)^{2}.
