Kua tāruatia ki te papatopenga
9+x^{2}=9
Tātaihia te 3 mā te pū o 2, kia riro ko 9.
x^{2}=9-9
Tangohia te 9 mai i ngā taha e rua.
x^{2}=0
Tangohia te 9 i te 9, ka 0.
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.
9+x^{2}=9
Tātaihia te 3 mā te pū o 2, kia riro ko 9.
9+x^{2}-9=0
Tangohia te 9 mai i ngā taha e rua.
x^{2}=0
Tangohia te 9 i te 9, ka 0.
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.
