I'm not quite sure what you mean. Mathcad can do either numeric math or symbolic math, so what you get depends on how you set up the worksheet. Could you be more specific about what you want to do.

Must be синхронность in action, Valery!  I was just thinking about givin a symbolic solve for the polynomial.  I've changed the sign of my third term to match yours (to ensure real roots).
