I'll spare you a picture of the symbolic solution (4 pages high, 16 pages wide), but this is what Mathcad 11 (with Maple) makes of it:

Many thanks, Luc. I need help with graphing the point of local min of the function f(x), the above.

It means what it says 😉

Mathcads symbolic simply is not capable enough to find a solution to this inequality.

EDIT: In your example which works OK Mathcad has only to deal with quadratic equations -> no problem
