expand-(2(-x+1))/(x^3)

expand

- \frac{2 ( - x + 1 )}{x ^{3}}

\frac{2}{x ^{2}} - \frac{2}{x ^{3}}

Solution steps

- \frac{2 ( - x + 1 )}{x ^{3}}

Expand

2 (- x + 1) : - 2 x + 2

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

Apply the fraction rule:

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

\frac{- 2 x + 2}{x ^{3}} = - (- \frac{2 x}{x ^{3}}) - (\frac{2}{x ^{3}})

= - (- \frac{2 x}{x ^{3}}) - (\frac{2}{x ^{3}})

Remove parentheses:

(a) = a, - (- a) = a

= \frac{2 x}{x ^{3}} - \frac{2}{x ^{3}}

Cancel

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

= \frac{2}{x ^{2}} - \frac{2}{x ^{3}}

(e^{\frac{jω}{2}} - e^{- \frac{jω}{2}})^{2}

cos (x^{2} + 3 y - 1) (2 x + 3 \frac{d y}{d x})

\frac{5 x ^{3} + 14 x ^{2} + 23 x + 6}{( s + 3 ) \cdot ( s - 3 ) \cdot ( s + 1 ) ^{2}}

1 + \frac{1}{s ( s + 2.2 )}

\frac{2 y ^{5} x - 3 y ^{3} x ^{2} - y x ^{4}}{( x ^{2} + y ^{2} ) ^{2}}
