x^2-1.21=0

Lösung

x^{2} - 1.21 = 0

x = \frac{11}{10}, x = - \frac{11}{10}

Dezimale

x = 1.1, x = - 1.1

Schritte zur Lösung

x^{2} - 1.21 = 0

Verschiebe

1.21

auf die rechte Seite

x^{2} = 1.21

Für

x^{2} = f (a)

sind die Lösungen

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

x = 1.21, x = - 1.21

1.21 = \frac{11}{10}

- 1.21 = - \frac{11}{10}

x = \frac{11}{10}, x = - \frac{11}{10}

- 4 x^{2} + 4 x - 9 = 0

so l v e f or x, f = x^{2} + 6 x - 1 f (x + h) - f \frac{( x )}{h}

so l v e f or x, q^{561.3} x^{2} - 22 x + 7 = 0

so l v e f or x, 5 x^{2} + 2 y^{2} + 4 x y + 4 y - 8 x + 14 = 0

5 x - 5 x^{2} - 1.25 = 0
