faktorisieren

- x^{2} + 81

- (x + 9) (x - 9)

Schritte zur Lösung

- x^{2} + 81

Klammere aus

- 1 : - (x^{2} - 81)

= - (x^{2} - 81)

Faktorisiere

x^{2} - 81 : (x + 9) (x - 9)

= - (x + 9) (x - 9)

72 + 36 n = 0

f a c t or a ln (a) - a ln (2 a)

\frac{2 x}{3} = \frac{x + 5}{2}

3 x^{2} + 10 x + 1 = 0

(3 x - 8) (x + 1) = 3
