b^2=18

Lösung

b^{2} = 18

b = 32, b = - 32

Dezimale

b = 4.24264 \dots, b = - 4.24264 \dots

Schritte zur Lösung

b^{2} = 18

Für

x^{2} = f (a)

sind die Lösungen

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

b = 18, b = - 18

18 = 32

- 18 = - 32

b = 32, b = - 32

6 x^{2} - 4 x - 26 + 10 x = 5 x^{2} - 26

x^{2} + 12 x + 26 = - 9

x^{2} + \frac{b}{a} x + \frac{c}{a} = 0

5 x^{2} + 34 x + 24 = 0

so l v e f or x, x^{2} + 2 x y + y^{2} + 2 x - 2 y - 1 = 0
