erweitern (t-1)2(\H(t-1)-\H(t-2))

Lösung

erweitern

(t - 1) 2 (H (t - 1) - H (t - 2))

2 t H (t - 1) - 2 t H (t - 2) - 2 H (t - 1) + 2 H (t - 2)

Schritte zur Lösung

(t - 1) \cdot 2 (H (t - 1) - H (t - 2))

= 2 (t - 1) (H (t - 1) - H (t - 2))

Multipliziere aus

(t - 1) (H (t - 1) - H (t - 2)) : t H (t - 1) - t H (t - 2) - H (t - 1) + H (t - 2)

= 2 (t H (t - 1) - t H (t - 2) - H (t - 1) + H (t - 2))

Multipliziere aus

2 (t H (t - 1) - t H (t - 2) - H (t - 1) + H (t - 2)) : 2 t H (t - 1) - 2 t H (t - 2) - 2 H (t - 1) + 2 H (t - 2)

= 2 t H (t - 1) - 2 t H (t - 2) - 2 H (t - 1) + 2 H (t - 2)
