Kua tāruatia ki te papatopenga
y=20x-0x^{2}-320
Whakareatia te 0 ki te 2, ka 0.
y=20x-0-320
Ko te tau i whakarea ki te kore ka hua ko te kore.
20x-0-320=y
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
20x-0=y+320
Me tāpiri te 320 ki ngā taha e rua.
20x=y+320+0
Me tāpiri te 0 ki ngā taha e rua.
20x=y+320
Tāpirihia te 320 ki te 0, ka 320.
\frac{20x}{20}=\frac{y+320}{20}
Whakawehea ngā taha e rua ki te 20.
x=\frac{y+320}{20}
Mā te whakawehe ki te 20 ka wetekia te whakareanga ki te 20.
x=\frac{y}{20}+16
Whakawehe y+320 ki te 20.
y=20x-0x^{2}-320
Whakareatia te 0 ki te 2, ka 0.
y=20x-0-320
Ko te tau i whakarea ki te kore ka hua ko te kore.
y=20x-320
Whakaraupapatia anō ngā kīanga tau.
