Prove that every polynomial having real coefficients and odd degree has a real root

Problem: Prove that every polynomial having real coefficients and odd degree has a real root This is a problem from a chapter 5.4 'applications of connectedness' in a book 'Principles of Topology(by Croom)' So you should prove by using the connectedness concept in Topology, maybe.
