Algebra Level 3

Find the term that does not contain the variable $x$ in the complete expansion of

$\left(x^2+x+\frac{1}{x}\right)^{10}.$

To be clear, if an expression is completely expanded, then all like terms have been combined together, leaving unlike terms in the final answer. For example,

$(a+1)^4=a^4+4a^3+6a^2+4a+1.$
