u^2=121

Lösung

u^{2} = 121

u = 11, u = - 11

Schritte zur Lösung

u^{2} = 121

Für

x^{2} = f (a)

sind die Lösungen

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

u = 121, u = - 121

121 = 11

- 121 = - 11

u = 11, u = - 11

9 y^{2} = 16

3 x (x - 2) = 12 x

25 x + 19 = 3 (x^{2} - 3)

x^{2} - 12 x - 18 = 0

2 x^{2} - 12 x + 8 = 0
