No xx Since Birth

Algebra Level 3

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

(x2+x+1x)10.\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=a4+4a3+6a2+4a+1.(a+1)^4=a^4+4a^3+6a^2+4a+1.
