B) 2
C) 4
D) 6
Correct Answer: A
Solution :
\[{{\left( x+\frac{1}{x} \right)}^{3}}+\left( x+\frac{1}{x} \right)=0\] \[\Rightarrow \] \[\left( x+\frac{1}{x} \right)\left[ {{\left( x+\frac{1}{x} \right)}^{2}}+1 \right]=0\] From above it is clear that the number of real roots of given equation is 0.You need to login to perform this action.
