How to display a long symbolic expression

[yhuang-3]

Hi all, if I have a long symbolic expression, that Mathcad returns the blank results, like the the coefficient of s^2 in this picture. If I want to show it, how can I get it? Thank you!

You can try additional symbolic operations such as simplify or collect, but if those don't work there's not a lot you can do.
