expand (5(-x+4))/(x^3)

expand

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

- \frac{5}{x ^{2}} + \frac{20}{x ^{3}}

Solution steps

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

Expand

5 (- x + 4) : - 5 x + 20

= \frac{- 5 x + 20}{x ^{3}}

Apply the fraction rule:

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

\frac{- 5 x + 20}{x ^{3}} = - \frac{5 x}{x ^{3}} + \frac{20}{x ^{3}}

= - \frac{5 x}{x ^{3}} + \frac{20}{x ^{3}}

Cancel

\frac{5 x}{x ^{3}} : \frac{5}{x ^{2}}

= - \frac{5}{x ^{2}} + \frac{20}{x ^{3}}

(\frac{- 20 - 2 y}{7})^{2}

\frac{2 s ^{2} + 6 s + 5}{( s + 2 ) ( s + 1 )}

x (e^{2 x} + x^{4})

(19 x^{2} - 2)^{\circ} (13 x - 9) (3)

\frac{9 x}{( x + 7 ) ( x - 8 )}
