Team Careers360 · Accepted Answer

Correct Answer: $\frac{1}{6}$

Solution : Given: $x+\frac{1}{x}=5$
Now, $\frac{x}{1+x+x^2}$
Divide the above expression by $x$ in numerator and denominator,
⇒ $\frac{1}{\frac{1}{x}+1+x}$
$=\frac{1}{x+\frac{1}{x}+1}$
$=\frac{1}{5+1}=\frac{1}{6}$
Hence, the correct answer is $\frac{1}{6}$.
