b^2=81

Lösung

b^{2} = 81

b = 9, b = - 9

Schritte zur Lösung

b^{2} = 81

Für

x^{2} = f (a)

sind die Lösungen

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

b = 81, b = - 81

81 = 9

- 81 = - 9

b = 9, b = - 9

x^{2} - 7 x + 0 = 0

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

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

6 x^{2} - 3 x - 12 = 0

- 2 x^{2} - 6 x - 2 = 0
