faktorisieren 9x^2-30+25

Lösung

faktorisieren

9 x^{2} - 30 + 25

(3 x + 5) (3 x - 5)

Schritte zur Lösung

9 x^{2} - 30 + 25

Addiere/Subtrahiere die Zahlen:

- 30 + 25 = - 5

= 9 x^{2} - 5

Schreibe

9 x^{2} - 5

um:

(3 x)^{2} - (5)^{2}

= (3 x)^{2} - (5)^{2}

Wende Formel zur Differenz von zwei Quadraten an:

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

(3 x)^{2} - (5)^{2} = (3 x + 5) (3 x - 5)

= (3 x + 5) (3 x - 5)
