mathcad symbolic solve - how to use fully resolved solution

I have an equation that has 3 real, numerical solutions.

I'd like to have the symbolic solutions for the values of wo which are positive. I think the symbolic expression i'm after is actually only the 2nd numerical solution 0.4897...

Mathcad finds a symbolic solution, but I don't know how to interpret the result or to use it.

Worksheet attached...

Many thanks for any help!
