Whakaoti mō f
\left\{\begin{matrix}\\f=-1\text{, }&\text{unconditionally}\\f\in \mathrm{R}\text{, }&n=0\end{matrix}\right.
Whakaoti mō n
\left\{\begin{matrix}\\n=0\text{, }&\text{unconditionally}\\n\in \mathrm{R}\text{, }&f=-1\end{matrix}\right.
Tohaina
Kua tāruatia ki te papatopenga
fn=-n
Tangohia te n mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
nf=-n
He hanga arowhānui tō te whārite.
\frac{nf}{n}=-\frac{n}{n}
Whakawehea ngā taha e rua ki te n.
f=-\frac{n}{n}
Mā te whakawehe ki te n ka wetekia te whakareanga ki te n.
f=-1
Whakawehe -n ki te n.
\left(f+1\right)n=0
Pahekotia ngā kīanga tau katoa e whai ana i te n.
n=0
Whakawehe 0 ki te f+1.
