Kua tāruatia ki te papatopenga
y=0x^{2}-2x-8
Whakareatia te 0 ki te 5, ka 0.
y=0-2x-8
Ko te tau i whakarea ki te kore ka hua ko te kore.
y=-8-2x
Tangohia te 8 i te 0, ka -8.
-8-2x=y
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
-2x=y+8
Me tāpiri te 8 ki ngā taha e rua.
\frac{-2x}{-2}=\frac{y+8}{-2}
Whakawehea ngā taha e rua ki te -2.
x=\frac{y+8}{-2}
Mā te whakawehe ki te -2 ka wetekia te whakareanga ki te -2.
x=-\frac{y}{2}-4
Whakawehe y+8 ki te -2.
y=0x^{2}-2x-8
Whakareatia te 0 ki te 5, ka 0.
y=0-2x-8
Ko te tau i whakarea ki te kore ka hua ko te kore.
y=-8-2x
Tangohia te 8 i te 0, ka -8.
