a^2= 1/2

Lösung

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

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

Dezimale

a = 0.70710 \dots, a = - 0.70710 \dots

Schritte zur Lösung

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

Für

x^{2} = f (a)

sind die Lösungen

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

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

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

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

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

5 x^{2} + 8 x + 80 = 0

4 y^{2} + 10 y - 5 = - y^{2} + 15 y + 5

B = (x + 8)^{2} + (x - 8)^{2} - (x + 2) (x - 2)

w^{2} = 8 w - 7

4 x = x^{2} - 6 x + 9
