Kua tāruatia ki te papatopenga
1000=a^{2}\times 1
Whakareatia te a ki te a, ka a^{2}.
a^{2}\times 1=1000
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
a^{2}=1000
Whakawehea ngā taha e rua ki te 1.
a=10\sqrt{10} a=-10\sqrt{10}
Tuhia te pūtakerua o ngā taha e rua o te whārite.
1000=a^{2}\times 1
Whakareatia te a ki te a, ka a^{2}.
a^{2}\times 1=1000
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
a^{2}\times 1-1000=0
Tangohia te 1000 mai i ngā taha e rua.
a^{2}-1000=0
Whakaraupapatia anō ngā kīanga tau.
a=\frac{0±\sqrt{0^{2}-4\left(-1000\right)}}{2}
Kei te āhua arowhānui tēnei whārite: ax^{2}+bx+c=0. Me whakakapi 1 mō a, 0 mō b, me -1000 mō c i te tikanga tātai pūrua, \frac{-b±\sqrt{b^{2}-4ac}}{2a}.
a=\frac{0±\sqrt{-4\left(-1000\right)}}{2}
Pūrua 0.
a=\frac{0±\sqrt{4000}}{2}
Whakareatia -4 ki te -1000.
a=\frac{0±20\sqrt{10}}{2}
Tuhia te pūtakerua o te 4000.
a=10\sqrt{10}
Nā, me whakaoti te whārite a=\frac{0±20\sqrt{10}}{2} ina he tāpiri te ±.
a=-10\sqrt{10}
Nā, me whakaoti te whārite a=\frac{0±20\sqrt{10}}{2} ina he tango te ±.
a=10\sqrt{10} a=-10\sqrt{10}
Kua oti te whārite te whakatau.
