x^2=784

Lösung

x^{2} = 784

x = 28, x = - 28

Schritte zur Lösung

x^{2} = 784

Für

x^{2} = f (a)

sind die Lösungen

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

x = 784, x = - 784

784 = 28

- 784 = - 28

x = 28, x = - 28

x = 4 - x^{2}

3 - x^{2} + 2 x = 0

\frac{1}{3} h^{2} + \frac{2}{9} h = - \frac{5}{18} h - \frac{7}{3} h^{2}

so l v e f or x, x^{2} + y^{2} + 8 x + 20 = 0

3 (2 + 3 x)^{2} - 9 (2 + 3 x) = 0
