Whakaoti mō a
a=x^{2}-4
Whakaoti mō x (complex solution)
x=-\sqrt{a+4}
x=\sqrt{a+4}
Whakaoti mō x
x=\sqrt{a+4}
x=-\sqrt{a+4}\text{, }a\geq -4
Graph
Tohaina
Kua tāruatia ki te papatopenga
-a=4-x^{2}
Tangohia te x^{2} mai i ngā taha e rua.
\frac{-a}{-1}=\frac{4-x^{2}}{-1}
Whakawehea ngā taha e rua ki te -1.
a=\frac{4-x^{2}}{-1}
Mā te whakawehe ki te -1 ka wetekia te whakareanga ki te -1.
a=x^{2}-4
Whakawehe -x^{2}+4 ki te -1.
