Kua tāruatia ki te papatopenga
\left(x-4\right)^{2}-17+17=17
Me tāpiri 17 ki ngā taha e rua o te whārite.
\left(x-4\right)^{2}=17
Mā te tango i te 17 i a ia ake anō ka toe ko te 0.
x-4=\sqrt{17} x-4=-\sqrt{17}
Tuhia te pūtakerua o ngā taha e rua o te whārite.
x-4-\left(-4\right)=\sqrt{17}-\left(-4\right) x-4-\left(-4\right)=-\sqrt{17}-\left(-4\right)
Me tāpiri 4 ki ngā taha e rua o te whārite.
x=\sqrt{17}-\left(-4\right) x=-\sqrt{17}-\left(-4\right)
Mā te tango i te -4 i a ia ake anō ka toe ko te 0.
x=\sqrt{17}+4
Tango -4 mai i \sqrt{17}.
x=4-\sqrt{17}
Tango -4 mai i -\sqrt{17}.
x=\sqrt{17}+4 x=4-\sqrt{17}
Kua oti te whārite te whakatau.
