Hello Roberto,
try
<< Algebra`InequalitySolve`
InequalitySolve[{x^2 - 2x + 1 == 0, x > 0}, x]
Out: x == 1

Betreff: [mg36095] Choose one solution in Mathematica
Dear all,
Assume that
x^2 - 2x + 1 = 0
The two solutions are x = -1 and x = 1.
If I assume that x > 0, then the only relevant solution would be x = 1.
How can I tell this to Mathematica?
Solve[x^2 - 2x + 1 = 0, x]
and then........
Many thanks.
Roberto De Santis
