x^{2} = \frac{1}{49}

Für

x^{2} = f (a)

sind die Lösungen

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

x = \frac{1}{49}, x = - \frac{1}{49}

\frac{1}{49} = \frac{1}{7}

- \frac{1}{49} = - \frac{1}{7}

x = \frac{1}{7}, x = - \frac{1}{7}

x^{2} + x = 272

2 x^{2} + 34 x - 336 = 0

x^{2} = 12 x + 28

3 r^{2} + 4 r + 10 = 0

w^{2} - 22 w + 121 = 81
