Kua tāruatia ki te papatopenga
x-4-\left(-4\right)=\sqrt{5}i-\left(-4\right) x-4-\left(-4\right)=-\sqrt{5}i-\left(-4\right)
Me tāpiri 4 ki ngā taha e rua o te whārite.
x=\sqrt{5}i-\left(-4\right) x=-\sqrt{5}i-\left(-4\right)
Mā te tango i te -4 i a ia ake anō ka toe ko te 0.
x=4+\sqrt{5}i
Tango -4 mai i i\sqrt{5}.
x=-\sqrt{5}i+4
Tango -4 mai i -i\sqrt{5}.
x=4+\sqrt{5}i x=-\sqrt{5}i+4
Kua oti te whārite te whakatau.
Ngā Tauira
whārite tapawhā
{ x } ^ { 2 } - 4 x - 5 = 0
Āhuahanga
4 \sin \theta \cos \theta = 2 \sin \theta
whārite paerangi
y = 3x + 4
