Whakaoti mō a
a=\left(b+6\right)^{2}+2
b+6\geq 0\text{ and }b\leq -6
Whakaoti mō b
b=-6
a=2
Tohaina
Kua tāruatia ki te papatopenga
\sqrt{a-2}+|b+6|-|b+6|=-|b+6|
Me tango |b+6| mai i ngā taha e rua o te whārite.
\sqrt{a-2}=-|b+6|
Mā te tango i te |b+6| i a ia ake anō ka toe ko te 0.
a-2=\left(b+6\right)^{2}
Pūruatia ngā taha e rua o te whārite.
a-2-\left(-2\right)=\left(b+6\right)^{2}-\left(-2\right)
Me tāpiri 2 ki ngā taha e rua o te whārite.
a=\left(b+6\right)^{2}-\left(-2\right)
Mā te tango i te -2 i a ia ake anō ka toe ko te 0.
a=\left(b+6\right)^{2}+2
Tango -2 mai i \left(b+6\right)^{2}.
