faktorisieren-x^2-8x+20

Lösung

faktorisieren

- x^{2} - 8 x + 20

- (x - 2) (x + 10)

Schritte zur Lösung

- x^{2} - 8 x + 20

Klammere aus

- 1 : - (x^{2} + 8 x - 20)

= - (x^{2} + 8 x - 20)

Faktorisiere

x^{2} + 8 x - 20 : (x - 2) (x + 10)

= - (x - 2) (x + 10)

r^{2} + 4 r + 5 = 0

4 x^{2} + 12 x = 8 x - 4

4 x^{2} - 12 x - 27 = 0

\frac{1}{16 π} ((8 + 2 π) x - 124 π) = 0

28 z - 16 - 7 z = 12
