expand (((x+2)x(x-1)))/(30)

expand

\frac{( ( x + 2 ) x ( x - 1 ) )}{30}

\frac{x ^{3}}{30} + \frac{x ^{2}}{30} - \frac{x}{15}

Solution steps

\frac{( x + 2 ) x ( x - 1 )}{30}

Expand

(x + 2) x (x - 1) : x^{3} + x^{2} - 2 x

= \frac{x ^{3} + x ^{2} - 2 x}{30}

Apply the fraction rule:

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

\frac{x ^{3} + x ^{2} - 2 x}{30} = \frac{x ^{3}}{30} + \frac{x ^{2}}{30} - \frac{2 x}{30}

= \frac{x ^{3}}{30} + \frac{x ^{2}}{30} - \frac{2 x}{30}

Cancel

\frac{2 x}{30} : \frac{x}{15}

= \frac{x ^{3}}{30} + \frac{x ^{2}}{30} - \frac{x}{15}

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

\frac{( 3 ln ( 6 ) - 5 ) ^{2}}{2}

\frac{4 x ^{2} - 4 x + 2}{( 2 x - 1 ) ^{2}}

\frac{( x + 5 ) ( 5 x + 10 )}{( x - 5 ) ^{2}}

4 w^{9 (7 w^{2} + 2 w)}
