faktorisieren 0.04x^2-0.09

Lösung

faktorisieren

0.04 x^{2} - 0.09

Lösung

(0.2 x + 0.3) (0.2 x - 0.3)

Schritte zur Lösung

0.04 x^{2} - 0.09

Schreibe

0.04 x^{2} - 0.09

um:

(0.04 x)^{2} - (0.09)^{2}

= (0.04 x)^{2} - (0.09)^{2}

Wende Formel zur Differenz von zwei Quadraten an:

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

(0.04 x)^{2} - (0.09)^{2} = (0.04 x + 0.09) (0.04 x - 0.09)

= (0.04 x + 0.09) (0.04 x - 0.09)

0.04 = 0.2

= (0.2 x + 0.09) (0.04 x - 0.09)

0.09 = 0.3

= (0.2 x + 0.3) (0.04 x - 0.09)

0.04 = 0.2

= (0.2 x + 0.3) (0.2 x - 0.09)

0.09 = 0.3

= (0.2 x + 0.3) (0.2 x - 0.3)
