In a few days i´m having a presentation in number theory. Are there any characteristics of polynomials with rational roots? Both the expression and graphical. How do I do this?

Sorry, did´nt get that :P But the teacher gave me a tip x^2+px+q=0 x=r1 V x=r2 (x-r1)(x-r2)=x2-x(r1+r2)+r2*r1 p=-(r2+r1) q=r2*r1
Check out the rational root theorem Rational root theorem - Wikipedia, the free encyclopedia
