Kua tāruatia ki te papatopenga
0x^{2}+216x-25=1694
Whakareatia te 0 ki te 6, ka 0.
0+216x-25=1694
Ko te tau i whakarea ki te kore ka hua ko te kore.
-25+216x=1694
Tangohia te 25 i te 0, ka -25.
216x=1694+25
Me tāpiri te 25 ki ngā taha e rua.
216x=1719
Tāpirihia te 1694 ki te 25, ka 1719.
x=\frac{1719}{216}
Whakawehea ngā taha e rua ki te 216.
x=\frac{191}{24}
Whakahekea te hautanga \frac{1719}{216} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 9.
