In mathematics, Darboux's theorem is a theorem in real analysis, named after Jean Gaston Darboux. It states that every function that results from the differentiation of another function has the intermediate value property: the image of an interval is also an interval. When ƒ is continuously differentiable (ƒ in C1([a,b])), this is a consequence of the intermediate value theorem. But even when ƒ′ is not continuous, Darboux's theorem places a severe restriction on what it can be. (Wikipedia).

The Factor theorem and polynumber evaluation 63 | Arithmetic and Geometry Math Foundations
We introduce the idea of evaluating a polynumber p at an integer c. This evaluation respects the additive and multiplicative structures of arithmetic. Then we state and prove the important Factor theorem of Descartes and its important Corollory relating a zero of a polynumber and a linear
