b^2=8

Lösung

b^{2} = 8

b = 22, b = - 22

Dezimale

b = 2.82842 \dots, b = - 2.82842 \dots

Schritte zur Lösung

b^{2} = 8

Für

x^{2} = f (a)

sind die Lösungen

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

b = 8, b = - 8

8 = 22

- 8 = - 22

b = 22, b = - 22

2 w^{2} + 5 w - 42 = 0

x^{2} - 11 x + 30 = 12

so l v e f or q, p = \frac{1}{2} q^{2} + 20

x^{2} + b x + 16 = 0

4 x^{2} - 11 x + 1 = 0
