r^2=9

Lösung

r^{2} = 9

r = 3, r = - 3

Schritte zur Lösung

r^{2} = 9

Für

x^{2} = f (a)

sind die Lösungen

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

r = 9, r = - 9

9 = 3

- 9 = - 3

r = 3, r = - 3

4 q (q + 2) + 10 = 0

q u a d r a t i c f or m u l a x^{2} - 2 x - 15 = 0

9 x^{2} + 54 x = - 83

a^{2} - a - 6 = 0

- 3 + (2 x + 1)^{2} = 2 - (x + 2)^{2}
