Whakaoti mō x_1
x_{1}=x^{2}-5
Whakaoti mō x (complex solution)
x=-\sqrt{x_{1}+5}
x=\sqrt{x_{1}+5}
Whakaoti mō x
x=\sqrt{x_{1}+5}
x=-\sqrt{x_{1}+5}\text{, }x_{1}\geq -5
Graph
Tohaina
Kua tāruatia ki te papatopenga
-x_{1}=5-x^{2}
Tangohia te x^{2} mai i ngā taha e rua.
\frac{-x_{1}}{-1}=\frac{5-x^{2}}{-1}
Whakawehea ngā taha e rua ki te -1.
x_{1}=\frac{5-x^{2}}{-1}
Mā te whakawehe ki te -1 ka wetekia te whakareanga ki te -1.
x_{1}=x^{2}-5
Whakawehe 5-x^{2} ki te -1.
