Kua tāruatia ki te papatopenga
\sqrt{x-2}-4-\left(-4\right)=-\left(-4\right)
Me tāpiri 4 ki ngā taha e rua o te whārite.
\sqrt{x-2}=-\left(-4\right)
Mā te tango i te -4 i a ia ake anō ka toe ko te 0.
\sqrt{x-2}=4
Tango -4 mai i 0.
x-2=16
Pūruatia ngā taha e rua o te whārite.
x-2-\left(-2\right)=16-\left(-2\right)
Me tāpiri 2 ki ngā taha e rua o te whārite.
x=16-\left(-2\right)
Mā te tango i te -2 i a ia ake anō ka toe ko te 0.
x=18
Tango -2 mai i 16.
