r^2=64

Lösung

r^{2} = 64

r = 8, r = - 8

Schritte zur Lösung

r^{2} = 64

Für

x^{2} = f (a)

sind die Lösungen

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

r = 64, r = - 64

64 = 8

- 64 = - 8

r = 8, r = - 8

so l v e f or y, x^{3} + x y^{2} = 2 - 3 y

x^{2} - 2 x - 33 = 0

x^{2} - 10 x + 89 = 0

x^{2} - 20 x + 52 = 0

- 7 x^{2} + 12 x + 86 = - 8 x^{2} - 6 x + 5
