x^2=4,9=9

Lösung

x^{2} = 4, 9 = 9

x = 2, x = - 2

Schritte zur Lösung

x^{2} = 4, 9 = 9

Für

x^{2} = f (a)

sind die Lösungen

x = f (a), - f (a)

x = 4, x = - 4

4 = 2

- 4 = - 2

x = 2, x = - 2

Check constrains

x = 2, x = - 2

14 - x^{2} = 0

8 k^{2} + 12 = - 2 k

so l v e f or x, f (x^{2}) = 3 x + 2

y^{2} - 2 y - 9 = 0

x^{2} = 1^{2} + 3^{2}
