(x^2-8)=0

Lösung

(x^{2} - 8) = 0

x = 22, x = - 22

Dezimale

x = 2.82842 \dots, x = - 2.82842 \dots

Schritte zur Lösung

(x^{2} - 8) = 0

x^{2} - 8 = 0

Verschiebe

8

auf die rechte Seite

x^{2} = 8

Für

x^{2} = f (a)

sind die Lösungen

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

x = 8, x = - 8

8 = 22

- 8 = - 22

x = 22, x = - 22

\frac{1}{2} - y^{2} + 3 = 0

a^{2} - 4 a - 5 = 0

9 x^{2} + 5 = 0

(2 x + 10)^{2} = 100 (1 - x)

80 = 3 x^{2} - x + 2
