x^{2}\left(x+1\right)+x+1
Do the grouping x^{3}+x^{2}+x+1=\left(x^{3}+x^{2}\right)+\left(x+1\right), and factor out x^{2} in x^{3}+x^{2}.
\left(x+1\right)\left(x^{2}+1\right)
Factor out common term x+1 by using distributive property. Polynomial x^{2}+1 is not factored since it does not have any rational roots.
