Kua tāruatia ki te papatopenga
-280x-698=0
Pahekotia te 32x me -312x, ka -280x.
-280x=698
Me tāpiri te 698 ki ngā taha e rua. Ko te tau i tāpiria he kore ka hua koia tonu.
x=\frac{698}{-280}
Whakawehea ngā taha e rua ki te -280.
x=-\frac{349}{140}
Whakahekea te hautanga \frac{698}{-280} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.
