m^2=121

Lösung

m^{2} = 121

m = 11, m = - 11

Schritte zur Lösung

m^{2} = 121

Für

x^{2} = f (a)

sind die Lösungen

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

m = 121, m = - 121

121 = 11

- 121 = - 11

m = 11, m = - 11

3 x^{2} + 12 = 39

(2 x + 1) (x - 5) = 0

x (x + 1) - 5 (x + 1) = (x + 1)

x^{2} - 4 x = - 9

(x - 3) \cdot (x + 8) = 0
