expand (5x(6480-5x^2))/(14)

expand

\frac{5 x ( 6480 - 5 x ^{2} )}{14}

- \frac{25 x ^{3}}{14} + \frac{16200 x}{7}

Solution steps

\frac{5 x ( 6480 - 5 x ^{2} )}{14}

Expand

5 x (6480 - 5 x^{2}) : 32400 x - 25 x^{3}

= \frac{32400 x - 25 x ^{3}}{14}

Apply the fraction rule:

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

\frac{32400 x - 25 x ^{3}}{14} = \frac{32400 x}{14} - \frac{25 x ^{3}}{14}

= \frac{32400 x}{14} - \frac{25 x ^{3}}{14}

Cancel

\frac{32400 x}{14} : \frac{16200 x}{7}

= \frac{16200 x}{7} - \frac{25 x ^{3}}{14}

Rewrite in standard form

= - \frac{25 x ^{3}}{14} + \frac{16200 x}{7}

2 + \frac{1}{2} cos (π (x + 1))

cos (2 t) - cos (2 (t - 2 π)) U (t - 2 π)

\frac{1}{x \cdot ( x - 1 ) \cdot ( x - 2 ) \cdot ( x - 3 )}

\frac{10 s + 2}{( s + 5 ) ( s + 1 )}
