Whakaoti mō x (complex solution)
x=-15\sqrt{21}i+75\approx 75-68.738635424i
x=75+15\sqrt{21}i\approx 75+68.738635424i

Kua tāruatia ki te papatopenga
x-75-\left(-75\right)=15\sqrt{21}i-\left(-75\right) x-75-\left(-75\right)=-15\sqrt{21}i-\left(-75\right)
Me tāpiri 75 ki ngā taha e rua o te whārite.
x=15\sqrt{21}i-\left(-75\right) x=-15\sqrt{21}i-\left(-75\right)
Mā te tango i te -75 i a ia ake anō ka toe ko te 0.
x=75+15\sqrt{21}i
Tango -75 mai i 15i\sqrt{21}.
x=-15\sqrt{21}i+75
Tango -75 mai i -15i\sqrt{21}.
x=75+15\sqrt{21}i x=-15\sqrt{21}i+75
Kua oti te whārite te whakatau.
