expand-(a(-a^2-1))/b

Solution

expand

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

Solution

\frac{a ^{3}}{b} + \frac{a}{b}

Solution steps

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

Expand

a (- a^{2} - 1) : - a^{3} - a

= - \frac{- a ^{3} - a}{b}

Apply the fraction rule:

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

\frac{- a ^{3} - a}{b} = - (- \frac{a ^{3}}{b}) - (- \frac{a}{b})

= - (- \frac{a ^{3}}{b}) - (- \frac{a}{b})

Apply rule

- (- a) = a

= \frac{a ^{3}}{b} + \frac{a}{b}
