Tohaina
Kua tāruatia ki te papatopenga
x-1=\sqrt{5} x-1=-\sqrt{5}
Tuhia te pūtakerua o ngā taha e rua o te whārite.
x-1-\left(-1\right)=\sqrt{5}-\left(-1\right) x-1-\left(-1\right)=-\sqrt{5}-\left(-1\right)
Me tāpiri 1 ki ngā taha e rua o te whārite.
x=\sqrt{5}-\left(-1\right) x=-\sqrt{5}-\left(-1\right)
Mā te tango i te -1 i a ia ake anō ka toe ko te 0.
x=\sqrt{5}+1
Tango -1 mai i \sqrt{5}.
x=1-\sqrt{5}
Tango -1 mai i -\sqrt{5}.
x=\sqrt{5}+1 x=1-\sqrt{5}
Kua oti te whārite te whakatau.
