x^2= 4/25

Lösung

x^{2} = \frac{4}{25}

x = \frac{2}{5}, x = - \frac{2}{5}

Dezimale

x = 0.4, x = - 0.4

Schritte zur Lösung

x^{2} = \frac{4}{25}

Für

x^{2} = f (a)

sind die Lösungen

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

x = \frac{4}{25}, x = - \frac{4}{25}

\frac{4}{25} = \frac{2}{5}

- \frac{4}{25} = - \frac{2}{5}

x = \frac{2}{5}, x = - \frac{2}{5}

x^{2} + 6 x + 20 = 0

0 = x^{2} - 3 x - 10

(x + 2)^{2} = 2

7 x^{2} + 20 x + 23 = 0

6 x^{2} + 12 x - 90 = 0
