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

expand

\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}

Solution steps

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

Expand

(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}

Expand

(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}

\frac{( a + c ) ( a - c )}{4 b}

(e^{x + y} + y e^{y}) d x

\frac{\partial}{\partial x} ((y) (x^{3} - 2 y^{2}))

5 a + \frac{5}{4} - 3 - 7 \frac{a}{6}

\frac{3 ( x + 5 )}{x + 4}
