Whakaoti mō b
b=0
Tohaina
Kua tāruatia ki te papatopenga
\left(0+3b\right)^{2}=0
Whakareatia te 0 ki te 4, ka 0.
\left(3b\right)^{2}=0
Ko te tau i tāpiria he kore ka hua koia tonu.
3^{2}b^{2}=0
Whakarohaina te \left(3b\right)^{2}.
9b^{2}=0
Tātaihia te 3 mā te pū o 2, kia riro ko 9.
b^{2}=0
Whakawehea ngā taha e rua ki te 9. Ko te kore i whakawehea ki te tau ehara te kore ka hua ko te kore.
b=0 b=0
Tuhia te pūtakerua o ngā taha e rua o te whārite.
b=0
Kua oti te whārite te whakatau. He ōrite ngā whakatau.
\left(0+3b\right)^{2}=0
Whakareatia te 0 ki te 4, ka 0.
\left(3b\right)^{2}=0
Ko te tau i tāpiria he kore ka hua koia tonu.
3^{2}b^{2}=0
Whakarohaina te \left(3b\right)^{2}.
9b^{2}=0
Tātaihia te 3 mā te pū o 2, kia riro ko 9.
b^{2}=0
Whakawehea ngā taha e rua ki te 9. Ko te kore i whakawehea ki te tau ehara te kore ka hua ko te kore.
b=\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}.
b=\frac{0±0}{2}
Tuhia te pūtakerua o te 0^{2}.
b=0
Whakawehe 0 ki te 2.
