x^2+1.4=3.6

Lösung

x^{2} + 1.4 = 3.6

x = \frac{11}{5}, x = - \frac{11}{5}

Dezimale

x = 1.48323 \dots, x = - 1.48323 \dots

auf die rechte Seite

x^{2} = 2.2

Für

x^{2} = f (a)

sind die Lösungen

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

x = 2.2, x = - 2.2

2.2 = \frac{11}{5}

- 2.2 = - \frac{11}{5}

x = \frac{11}{5}, x = - \frac{11}{5}
