Kua tāruatia ki te papatopenga
0x^{2}+90x-18000=0
Whakareatia te 0 ki te 1, ka 0.
0+90x-18000=0
Ko te tau i whakarea ki te kore ka hua ko te kore.
-18000+90x=0
Tangohia te 18000 i te 0, ka -18000.
90x=18000
Me tāpiri te 18000 ki ngā taha e rua. Ko te tau i tāpiria he kore ka hua koia tonu.
x=\frac{18000}{90}
Whakawehea ngā taha e rua ki te 90.
x=200
Whakawehea te 18000 ki te 90, kia riro ko 200.
