(0.3 r + 0.5 s) (0.3 r - 0.5 s)

Schritte zur Lösung

0.09 r^{2} - 0.25 s^{2}

Schreibe

0.09 r^{2} - 0.25 s^{2}

um:

(0.09 r)^{2} - (0.25 s)^{2}

= (0.09 r)^{2} - (0.25 s)^{2}

Wende Formel zur Differenz von zwei Quadraten an:

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

(0.09 r)^{2} - (0.25 s)^{2} = (0.09 r + 0.25 s) (0.09 r - 0.25 s)

= (0.09 r + 0.25 s) (0.09 r - 0.25 s)

0.09 = 0.3

= (0.3 r + 0.25 s) (0.09 r - 0.25 s)

0.25 = 0.5

= (0.3 r + 0.5 s) (0.09 r - 0.25 s)

0.09 = 0.3

= (0.3 r + 0.5 s) (0.3 r - 0.25 s)

0.25 = 0.5

= (0.3 r + 0.5 s) (0.3 r - 0.5 s)
