((x+3)(x-3))^2=100

Lösung

((x + 3) (x - 3))^{2} = 100

x = 19, x = - 19, x = i, x = - i

Schritte zur Lösung

((x + 3) (x - 3))^{2} = 100

Für

(g (x))^{2} = f (a)

sind die Lösungen

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

Löse

(x + 3) (x - 3) = 100 : x = 19, x = - 19

Löse

(x + 3) (x - 3) = - 100 : x = i, x = - i

Die Lösungen sind

x = 19, x = - 19, x = i, x = - i

c^{3} = - 64

x^{4} + 6 x^{3} + 3 x^{2} - 16 x + 6 = 0

- x^{3} - 6 x^{2} - 12 x - 8 = 0

x^{3} + 5 x^{2} - 6 x = 0

2 (x + 6) (x^{2} + 36) = 0
