Answer:
[tex](x^2+1)(x + 1)[/tex]
Step-by-step explanation:
Factor [tex]x^3 + x^2 + x + 1[/tex] by grouping
Group first two terms and last two terms
[tex](x^3 + x^2) + (x + 1)[/tex]
Factor out GCF from each group . when we factor out GCF , divide each term by GCF
[tex]x^2(x+1) + 1(x + 1)[/tex]
Factor out x+1
[tex](x^2+1)(x + 1)[/tex]
