expand ((p-l)D)/(lv^2)

expand

\frac{( p - l ) D}{l v ^{2}}

\frac{p D}{l v ^{2}} - \frac{D}{v ^{2}}

Solution steps

\frac{( p - l ) D}{l v ^{2}}

Expand

(p - l) D : p D - l D

= \frac{p D - l D}{l v ^{2}}

Apply the fraction rule:

\frac{a \pm b}{c} = \frac{a}{c} \pm \frac{b}{c}

\frac{p D - l D}{l v ^{2}} = \frac{p D}{l v ^{2}} - \frac{l D}{l v ^{2}}

= \frac{p D}{l v ^{2}} - \frac{l D}{l v ^{2}}

Cancel

\frac{l D}{l v ^{2}} : \frac{D}{v ^{2}}

= \frac{p D}{l v ^{2}} - \frac{D}{v ^{2}}

, (- 7 + 2 i)

(2 x + \frac{1}{y} - \frac{y}{x ^{2}}) d x + (2 y + \frac{1}{x} - \frac{x}{y ^{2}}) d y

u \frac{\partial}{\partial x} ((x - 2 y) t)

\frac{3 - s ^{3} - 9 s}{( s ^{2} + 9 ) ( s ^{2} + 4 )}

\frac{5 x ^{2} + 17 x + 12}{( x + 3 ) ^{2} ( x - 3 )}
