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