Question

how to divide x cube + 1 by x+1

Answer 1

Hi ,

**************************************

We know the algebraic identity,

a³ + b³ = ( a + b ) ( a² - ab + b² )

*****************************************

Now ,

( x³ + 1 ) / ( x + 1 )

= ( x³ + 1³ )/ ( x + 1 )

= [ ( x + 1 ) ( x² - x + 1² )]/( x + 1 )

= ( x² - x + 1 )

I hope this helps you.
