c^2=13

Lösung

c^{2} = 13

c = 13, c = - 13

Dezimale

c = 3.60555 \dots, c = - 3.60555 \dots

Schritte zur Lösung

c^{2} = 13

Für

x^{2} = f (a)

sind die Lösungen

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

c = 13, c = - 13

(x + 5) (x + 1) = x - 2

so l v e f or x, x^{2} + y^{2} = 100

4 x^{2} + 42 = 7 x^{2} - 54

(x^{2} + x) = 0

1 (- 3) = (6 x + 5) (- 9 x - 6)
