Kua tāruatia ki te papatopenga
x^{2}=\frac{6}{4}
Whakawehea ngā taha e rua ki te 4.
x^{2}=\frac{3}{2}
Whakahekea te hautanga \frac{6}{4} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.
x=\frac{\sqrt{6}}{2} x=-\frac{\sqrt{6}}{2}
Tuhia te pūtakerua o ngā taha e rua o te whārite.
x^{2}=\frac{6}{4}
Whakawehea ngā taha e rua ki te 4.
x^{2}=\frac{3}{2}
Whakahekea te hautanga \frac{6}{4} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.
x^{2}-\frac{3}{2}=0
Tangohia te \frac{3}{2} mai i ngā taha e rua.
x=\frac{0±\sqrt{0^{2}-4\left(-\frac{3}{2}\right)}}{2}
Kei te āhua arowhānui tēnei whārite: ax^{2}+bx+c=0. Me whakakapi 1 mō a, 0 mō b, me -\frac{3}{2} mō c i te tikanga tātai pūrua, \frac{-b±\sqrt{b^{2}-4ac}}{2a}.
x=\frac{0±\sqrt{-4\left(-\frac{3}{2}\right)}}{2}
Pūrua 0.
x=\frac{0±\sqrt{6}}{2}
Whakareatia -4 ki te -\frac{3}{2}.
x=\frac{\sqrt{6}}{2}
Nā, me whakaoti te whārite x=\frac{0±\sqrt{6}}{2} ina he tāpiri te ±.
x=-\frac{\sqrt{6}}{2}
Nā, me whakaoti te whārite x=\frac{0±\sqrt{6}}{2} ina he tango te ±.
x=\frac{\sqrt{6}}{2} x=-\frac{\sqrt{6}}{2}
Kua oti te whārite te whakatau.
