It has been stated a simple extension of the Rolle?s theorem. This extension permits to determine the amount of numbers  in which  in a given interval using the characteristics of the function  in that interval. The extension has been proved and the geometric interpretation is presented. Illustrative examples have been developed for each of the cases that can be obtained by applying the extension. The relation of this theorem with the problem of multiple internal rates of return (IRR) is presented.
