Question

Evaluate the product (x-1) (x2+1+x)

Answer 1

$(x-1)( x^{2} +x+1) =(x-1)(x+1) + (x-1)( x^{2} )$
                                
                                   = $(x^{2} -1)+ x^{3}-[tex] x^{2}$ [/tex]
              
                                   = $x^{3} + x^{2} -[tex] x^{2}$ -1[/tex]
      
                                   = $x^{3}-1$

Answer 2

Heya,

(x-1)(x^2 + 1 + x)
=x^3 + x + x^2 - x^2 -1 - x
=x^3 - 1
