Whakaoti mō b
b=x^{2}-8y+2
Whakaoti mō x (complex solution)
x=-\sqrt{8y+b-2}
x=\sqrt{8y+b-2}
Whakaoti mō x
x=\sqrt{8y+b-2}
x=-\sqrt{8y+b-2}\text{, }b\geq 2-8y

Kua tāruatia ki te papatopenga
2-b=8y-x^{2}
Tangohia te x^{2} mai i ngā taha e rua.
-b=8y-x^{2}-2
Tangohia te 2 mai i ngā taha e rua.
-b=-x^{2}+8y-2
He hanga arowhānui tō te whārite.
\frac{-b}{-1}=\frac{-x^{2}+8y-2}{-1}
Whakawehea ngā taha e rua ki te -1.
b=\frac{-x^{2}+8y-2}{-1}
Mā te whakawehe ki te -1 ka wetekia te whakareanga ki te -1.
b=x^{2}-8y+2
Whakawehe 8y-x^{2}-2 ki te -1.
