Lösung

x^{2} = \frac{81}{169}

x = \frac{9}{13}, x = - \frac{9}{13}

Dezimale

x = 0.69230 \dots, x = - 0.69230 \dots

Schritte zur Lösung

x^{2} = \frac{81}{169}

Für

x^{2} = f (a)

sind die Lösungen

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

x = \frac{81}{169}, x = - \frac{81}{169}

\frac{81}{169} = \frac{9}{13}

- \frac{81}{169} = - \frac{9}{13}

x = \frac{9}{13}, x = - \frac{9}{13}

5 x^{2} - 4 x - 10 = 0

2 x^{2} = 6 x - 6

12 x^{2} - 72 x - 84 = 0

n^{2} - 159 = 10

x^{2} + 18 = - 6 x
