1-2x+3x^{2}-x^{2}=-2x+1
Tangohia te x^{2} mai i ngā taha e rua.
1-2x+2x^{2}=-2x+1
Pahekotia te 3x^{2} me -x^{2}, ka 2x^{2}.
1-2x+2x^{2}+2x=1
Me tāpiri te 2x ki ngā taha e rua.
1+2x^{2}=1
Pahekotia te -2x me 2x, ka 0.
2x^{2}=1-1
Tangohia te 1 mai i ngā taha e rua.
2x^{2}=0
Tangohia te 1 i te 1, ka 0.
x^{2}=0
Whakawehea ngā taha e rua ki te 2. Ko te kore i whakawehea ki te tau ehara te kore ka hua ko te kore.
x=0 x=0
Tuhia te pūtakerua o ngā taha e rua o te whārite.
x=0
Kua oti te whārite te whakatau. He ōrite ngā whakatau.
1-2x+3x^{2}-x^{2}=-2x+1

2x^{2}=0
Tangohia te 1 i te 1, ka 0.
x^{2}=0
Whakawehea ngā taha e rua ki te 2. Ko te kore i whakawehea ki te tau ehara te kore ka hua ko te kore.
x=\frac{0±\sqrt{0^{2}}}{2}
Kei te āhua arowhānui tēnei whārite: ax^{2}+bx+c=0. Me whakakapi 1 mō a, 0 mō b, me 0 mō c i te tikanga tātai pūrua, \frac{-b±\sqrt{b^{2}-4ac}}{2a}.
x=\frac{0±0}{2}
Tuhia te pūtakerua o te 0^{2}.
x=0
Whakawehe 0 ki te 2.
