t^2=9

Lösung

t^{2} = 9

t = 3, t = - 3

Schritte zur Lösung

t^{2} = 9

Für

x^{2} = f (a)

sind die Lösungen

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

t = 9, t = - 9

9 = 3

- 9 = - 3

t = 3, t = - 3

x^{2} - 3 x = 5 x - x^{2}

x (3 x - 4) = 1

x^{2} + 0.000018 x - 0.0000018 = 0

4 x^{2} + 40 x + 280 = 0

- 9 x + 2 x^{2} - 18 = - 3 x
