r^2=100

Lösung

r^{2} = 100

r = 10, r = - 10

Schritte zur Lösung

r^{2} = 100

Für

x^{2} = f (a)

sind die Lösungen

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

r = 100, r = - 100

100 = 10

- 100 = - 10

r = 10, r = - 10

so l v e f or x, 2 x^{2} - \frac{k x}{2} + \frac{1}{32} = 0

10 x^{2} + 19 x + 7 = 0

(x^{2} - 2 x) = 0

4 x^{2} - 10 x + 5 = x^{2} + 4 x - 3

x^{2} + 18 x + 72 = 0
