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

expand

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

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

Solution steps

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

Expand

3 (x + 1) : 3 x + 3

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

Expand

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

= \frac{x ^{3} + x - x ^{2} - 1}{3 x + 3}

\frac{- ( - 1 ) ^{x - 1} - 15 + 4 x}{2}

\frac{4 ( x + h ) + 7}{3 ( x + h ) - 2}

\frac{a ( a + 1 ) ( a + 2 )}{6}
