faktorisieren (x-9)^2-2

Lösung

faktorisieren

(x - 9)^{2} - 2

Lösung

(x - 9 + 2) (x - 9 - 2)

Schritte zur Lösung

(x - 9)^{2} - 2

Wende Radikal Regel an:

a = (a)^{2}

2 = (2)^{2}

= (x - 9)^{2} - (2)^{2}

Wende Formel zur Differenz von zwei Quadraten an:

x^{2} - y^{2} = (x + y) (x - y)

(x - 9)^{2} - (2)^{2} = ((x - 9) + 2) ((x - 9) - 2)

= ((x - 9) + 2) ((x - 9) - 2)

Fasse zusammen

= (x + 2 - 9) (x - 9 - 2)
