factor ((1-r^3))/(1-r)

Solution

factor

\frac{( 1 - r ^{3} )}{1 - r}

Solution

r^{2} + r + 1

Solution steps

\frac{1 - r ^{3}}{1 - r}

Factor

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

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

Cancel

- \frac{( r - 1 ) ( r ^{2} + r + 1 )}{1 - r} : r^{2} + r + 1

= r^{2} + r + 1
