s^2=169

Lösung

s^{2} = 169

s = 13, s = - 13

Schritte zur Lösung

s^{2} = 169

Für

x^{2} = f (a)

sind die Lösungen

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

s = 169, s = - 169

169 = 13

- 169 = - 13

s = 13, s = - 13

\frac{x ^{2}}{2} + \frac{4 x}{3} = 6

x^{2} + 9 x + 16 = 2 x + 6

5 x^{2} - 7 x + 4 = 0

9 x^{2} = 63 x

x^{2} - 2 x = 120
