x^2= 25/4

Lösung

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

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

Dezimale

x = 2.5, x = - 2.5

Schritte zur Lösung

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

Für

x^{2} = f (a)

sind die Lösungen

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

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

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

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

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

9 - 15 x^{2} = 13 + 7 x^{2}

16 d^{2} - 81 = 0

0 = - x^{2} - 4

x^{2} + 29 = - 12 x

x^{2} + 4 = 1
