x\left(x-6\right)=0
Tauwehea te x.
x=0 x=6
Hei kimi otinga whārite, me whakaoti te x=0 me te x-6=0.
x^{2}-6x=0
Ko ngā whārite katoa o te āhua ax^{2}+bx+c=0 ka taea te whakaoti mā te whakamahi i te tikanga tātai pūrua: \frac{-b±\sqrt{b^{2}-4ac}}{2a}. E rua ngā otinga ka puta i te tikanga tātai pūrua, ko tētahi ina he tāpiri a ±, ā, ko tētahi ina he tango.
x=\frac{-\left(-6\right)±\sqrt{\left(-6\right)^{2}}}{2}
Kei te āhua arowhānui tēnei whārite: ax^{2}+bx+c=0. Me whakakapi 1 mō a, -6 mō b, me 0 mō c i te tikanga tātai pūrua, \frac{-b±\sqrt{b^{2}-4ac}}{2a}.
x=\frac{-\left(-6\right)±6}{2}
Tuhia te pūtakerua o te \left(-6\right)^{2}.
x=\frac{6±6}{2}
Ko te tauaro o -6 ko 6.
x=\frac{12}{2}
Nā, me whakaoti te whārite x=\frac{6±6}{2} ina he tāpiri te ±. Tāpiri 6 ki te 6.
x=6
Whakawehe 12 ki te 2.
x=\frac{0}{2}
Nā, me whakaoti te whārite x=\frac{6±6}{2} ina he tango te ±. Tango 6 mai i 6.
x=0
Whakawehe 0 ki te 2.
x=6 x=0
Kua oti te whārite te whakatau.
x^{2}-6x=0
Ko ngā whārite pūrua pēnei i tēnei nā ka taea te whakaoti mā te whakaoti i te pūrua. Hei whakaoti i te pūrua, ko te whārite me mātua tuhi ki te āhua x^{2}+bx=c.
x^{2}-6x+\left(-3\right)^{2}=\left(-3\right)^{2}
Whakawehea te -6, te tau whakarea o te kīanga tau x, ki te 2 kia riro ai te -3. Nā, tāpiria te pūrua o te -3 ki ngā taha e rua o te whārite. Mā konei e pūrua tika tonu ai te taha mauī o te whārite.
x^{2}-6x+9=9
Pūrua -3.
\left(x-3\right)^{2}=9
Tauwehea x^{2}-6x+9. Ko te tikanga pūnoa, ina ko x^{2}+bx+c he pūrua tika pūrua tika pū, ka taea taua mea te tauwehea i ngā wā katoa hei \left(x+\frac{b}{2}\right)^{2}.
\sqrt{\left(x-3\right)^{2}}=\sqrt{9}
Tuhia te pūtakerua o ngā taha e rua o te whārite.
x-3=3 x-3=-3
Whakarūnātia.
x=6 x=0
Me tāpiri 3 ki ngā taha e rua o te whārite.
