r^2=17

Lösung

r^{2} = 17

r = 17, r = - 17

Dezimale

r = 4.12310 \dots, r = - 4.12310 \dots

Schritte zur Lösung

r^{2} = 17

Für

x^{2} = f (a)

sind die Lösungen

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

r = 17, r = - 17

r^{2} = 14

r^{2} = 12

r^{2} = 13

so l v e f or x, x^{2} + 10 x + 7 x y - y^{2} = 9

x^{2} - 6 x = - 11
