i can't find the resonant frequency in a rlc circuit

Question

I have an exercise where I have to find the resonant frequency but the equation can't be solve.

What happen in those cases? It is possible to say that te RCL circuit does not have a resonant frequency?

\$\begingroup\$ What equation can't be solved? Show us the equation. \$\endgroup\$

I resolved it. It's something called a biquadratic equation. We can do a sustitution z = w^2 to transform it to a standard quadratic equation.
