x^{2} + (\frac{- 1}{2})^{2} = 1

Lösung

x = \frac{3}{2}, x = - \frac{3}{2}

+1

Dezimale

x = 0.86602 \dots, x = - 0.86602 \dots

Schritte zur Lösung

x^{2} + (\frac{- 1}{2})^{2} = 1

Schreibe

x^{2} + (\frac{- 1}{2})^{2}

um:

x^{2} + \frac{1}{4}

x^{2} + \frac{1}{4} = 1

Verschiebe

\frac{1}{4}

auf die rechte Seite

x^{2} = 1 - \frac{1}{4}

Vereinfache

1 - \frac{1}{4} : \frac{3}{4}

Für

x^{2} = f (a)

sind die Lösungen

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

x = \frac{3}{4}, x = - \frac{3}{4}

\frac{3}{4} = \frac{3}{2}

- \frac{3}{4} = - \frac{3}{2}

x = \frac{3}{2}, x = - \frac{3}{2}
