Kua tāruatia ki te papatopenga
1-x+\sqrt{2}=0
Tātaihia te -1 mā te pū o 2, kia riro ko 1.
-x+\sqrt{2}=-1
Tangohia te 1 mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
-x=-1-\sqrt{2}
Tangohia te \sqrt{2} mai i ngā taha e rua.
-x=-\sqrt{2}-1
He hanga arowhānui tō te whārite.
\frac{-x}{-1}=\frac{-\sqrt{2}-1}{-1}
Whakawehea ngā taha e rua ki te -1.
x=\frac{-\sqrt{2}-1}{-1}
Mā te whakawehe ki te -1 ka wetekia te whakareanga ki te -1.
x=\sqrt{2}+1
Whakawehe -1-\sqrt{2} ki te -1.
