9 = b^{2}

b = 3, b = - 3

Schritte zur Lösung

9 = b^{2}

Tausche die Seiten

b^{2} = 9

Für

x^{2} = f (a)

sind die Lösungen

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

b = 9, b = - 9

9 = 3

- 9 = - 3

b = 3, b = - 3

4 - (5 x + 3)^{2} = 3

6 x^{2} + 5 x - 18 = - 7

w^{2} = - 64

x^{2} - 10 x + 39 = 0

2 x^{2} + 9 x + 20 = 0
