y^2= 1/2

Lösung

y^{2} = \frac{1}{2}

y = \frac{1}{2}, y = - \frac{1}{2}

Dezimale

y = 0.70710 \dots, y = - 0.70710 \dots

Schritte zur Lösung

y^{2} = \frac{1}{2}

Für

x^{2} = f (a)

sind die Lösungen

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

y = \frac{1}{2}, y = - \frac{1}{2}

\frac{1}{2} = \frac{1}{2}

- \frac{1}{2} = - \frac{1}{2}

y = \frac{1}{2}, y = - \frac{1}{2}

10 = x^{2} - 3 x

2 (x + 6)^{2} - 5 = 45

4 x^{2} + 3 = 9 x

25 x^{2} - 70 x + 49 = 0

x (\frac{x}{2}) = 800
