How To Prove Real Roots. whether the discriminant is greater than zero, equal to zero or less than zero can be used to determine if a quadratic equation has no real roots, real and equal. follow these general steps to ensure that you find every root: find the real roots of each equation by factoring or using the quadratic formula. Use the rational root theorem to list all possible rational roots. a) show that a polynomial of degree 3 has at most three real roots. In the special case that f is a. B) show that a polynomial of degree n has at most n real. to prove existence of roots of a continuous function, you can exhibit changes of sign. here’s how descartes’s rule of signs can give you the numbers of possible real roots, both positive and negative: in your example, computing f(±2) = 3 and f(0) = −1 gives that f has one root each in (−2, 0) and (0, +2).
