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