expand ((9x-2)^3)/7

expand

\frac{( 9 x - 2 ) ^{3}}{7}

\frac{729 x ^{3}}{7} - \frac{486 x ^{2}}{7} + \frac{108 x}{7} - \frac{8}{7}

Solution steps

\frac{( 9 x - 2 ) ^{3}}{7}

(9 x - 2)^{3} = 729 x^{3} - 486 x^{2} + 108 x - 8

= \frac{729 x ^{3} - 486 x ^{2} + 108 x - 8}{7}

Apply the fraction rule:

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

\frac{729 x ^{3} - 486 x ^{2} + 108 x - 8}{7} = \frac{729 x ^{3}}{7} - \frac{486 x ^{2}}{7} + \frac{108 x}{7} - \frac{8}{7}

= \frac{729 x ^{3}}{7} - \frac{486 x ^{2}}{7} + \frac{108 x}{7} - \frac{8}{7}

\frac{1}{v ( m - 3 )}

- 2 (2 z + 1 = 26)

\frac{b}{x ( x + a )}

e^{x} (x - 1) (2 x - 1)

\frac{1}{( a - x ) ^{2}}
