Kua tāruatia ki te papatopenga
y=0x^{2}+2x-9
Whakareatia te 0 ki te 1, ka 0.
y=0+2x-9
Ko te tau i whakarea ki te kore ka hua ko te kore.
y=-9+2x
Tangohia te 9 i te 0, ka -9.
-9+2x=y
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
2x=y+9
Me tāpiri te 9 ki ngā taha e rua.
\frac{2x}{2}=\frac{y+9}{2}
Whakawehea ngā taha e rua ki te 2.
x=\frac{y+9}{2}
Mā te whakawehe ki te 2 ka wetekia te whakareanga ki te 2.
y=0x^{2}+2x-9
Whakareatia te 0 ki te 1, ka 0.
y=0+2x-9
Ko te tau i whakarea ki te kore ka hua ko te kore.
y=-9+2x
Tangohia te 9 i te 0, ka -9.
