Whakaoti mō c
c=\frac{x^{2}-20}{5}
Whakaoti mō x (complex solution)
x=-\sqrt{5\left(c+4\right)}
x=\sqrt{5\left(c+4\right)}
Whakaoti mō x
x=\sqrt{5\left(c+4\right)}
x=-\sqrt{5\left(c+4\right)}\text{, }c\geq -4
Graph
Tohaina
Kua tāruatia ki te papatopenga
-5c=20-x^{2}
Tangohia te x^{2} mai i ngā taha e rua.
\frac{-5c}{-5}=\frac{20-x^{2}}{-5}
Whakawehea ngā taha e rua ki te -5.
c=\frac{20-x^{2}}{-5}
Mā te whakawehe ki te -5 ka wetekia te whakareanga ki te -5.
c=\frac{x^{2}}{5}-4
Whakawehe 20-x^{2} ki te -5.
