Answer
Yes
Work Step by Step
We know that the impedance of $RLC$ circuit is given as $Z=\sqrt{R^2+(X_L-X_c)^2}$.
The impedance depends on $X_L$ and $X_C$. At resonance $X_L=X_C$.
Below the resonance condition $X_L\lt X_C$, so we have $X_L-X_C\lt 0$.
Beyond the resonance condition $X_L\gt X_C$, so we have $X_L-X_C\gt 0$.
Thus, there are two values of $\omega$ for which $(X_L-X_C)^2$ have the same value; one is below the resonance frequency and the other is above the resonance frequency.
