b^2=49

Lösung

b^{2} = 49

b = 7, b = - 7

Schritte zur Lösung

b^{2} = 49

Für

x^{2} = f (a)

sind die Lösungen

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

b = 49, b = - 49

49 = 7

- 49 = - 7

b = 7, b = - 7

c^{2} - 16 c + 64 = 0

2 x^{2} + 16 x - 70 = - 4

x^{2} - 10 x + 25 = 36

3 n^{2} + 24 n = - 48

4 x^{2} + 4 (k - 2) x + k = 0
