Whakaoti mō n_8
n_{8}=n\left(n+8\right)
Whakaoti mō n
n=\sqrt{n_{8}+16}-4
n=-\sqrt{n_{8}+16}-4\text{, }n_{8}\geq -16
Tohaina
Kua tāruatia ki te papatopenga
8n-n_{8}=-n^{2}
Tangohia te n^{2} mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
-n_{8}=-n^{2}-8n
Tangohia te 8n mai i ngā taha e rua.
\frac{-n_{8}}{-1}=-\frac{n\left(n+8\right)}{-1}
Whakawehea ngā taha e rua ki te -1.
n_{8}=-\frac{n\left(n+8\right)}{-1}
Mā te whakawehe ki te -1 ka wetekia te whakareanga ki te -1.
n_{8}=n\left(n+8\right)
Whakawehe -n\left(8+n\right) ki te -1.
