erweitern ((r+pB)(1+lsB))/((1+rpB)(l+sB))

Lösung

erweitern

\frac{( r + pB ) ( 1 + l s B )}{( 1 + r pB ) ( l + s B )}

\frac{r + l r B s + pB + lp B ^{2} s}{l + B s + l r pB + r p B ^{2} s}

Schritte zur Lösung

\frac{( r + pB ) ( 1 + l s B )}{( 1 + r pB ) ( l + s B )}

(1 + r pB) (l + s B) : l + B s + l r pB + r p B^{2} s

= \frac{( r + pB ) ( lB s + 1 )}{l + B s + l r pB + r p B ^{2} s}

Multipliziere aus

(r + pB) (1 + l s B) : r + l r B s + pB + lp B^{2} s

= \frac{r + l r B s + pB + lp B ^{2} s}{l + B s + l r pB + r p B ^{2} s}
