an elementary real-algebraic proof via Sturm chains.
... 1.5. All computations can be carried out using Sturm chains according to Theorem 1.2. By iterated bisection we can thus approximate all roots to any desired precision. Remark 1.9 (computability). In the real-algebraic setting of this article we consider the field operations (a, b) 7→ a + b, a 7→ −a, ...
