Tohaina
Kua tāruatia ki te papatopenga
0x^{2}+5x-8=0
Whakareatia te 0 ki te 25, ka 0.
0+5x-8=0
Ko te tau i whakarea ki te kore ka hua ko te kore.
-8+5x=0
Tangohia te 8 i te 0, ka -8.
5x=8
Me tāpiri te 8 ki ngā taha e rua. Ko te tau i tāpiria he kore ka hua koia tonu.
x=\frac{8}{5}
Whakawehea ngā taha e rua ki te 5.
