x^2= 4/49

Lösung

x^{2} = \frac{4}{49}

x = \frac{2}{7}, x = - \frac{2}{7}

Dezimale

x = 0.28571 \dots, x = - 0.28571 \dots

Schritte zur Lösung

x^{2} = \frac{4}{49}

Für

x^{2} = f (a)

sind die Lösungen

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

x = \frac{4}{49}, x = - \frac{4}{49}

\frac{4}{49} = \frac{2}{7}

- \frac{4}{49} = - \frac{2}{7}

x = \frac{2}{7}, x = - \frac{2}{7}

9^{2} + 5^{2} = x^{2}

3 x^{2} = 10

ab x^{2} + 4 b^{2} x + 3 a^{2} x + 12 ab = 0

3 x^{2} = - 5

so l v e f or b, y = (a - \frac{b}{x})^{2}
