For example, given x 2 −2x+1=0, the polynomial x 2 −2x+1 has two variations of the sign, and hence the equation has either two positive real roots or none. The factored form of the equation is (x−1) 2 =0, and thus 1 is a root of multiplicity 2. To illustrate the variety of …

Web[Since the negative roots of the polynomial equation f(x) = 0 are positive roots of the equation f(-x) = 0, the rule can be readily applied to help count the negative roots as well.] Descartes' Rule is a staple of high-school algebra courses, but a proof is seldom seen, even at the college level -- this sort of material from the "theory of equations" being seriously … WebHint: by Descartes' rule of signs the equation has no positive real roots, and at most $2$ negative ones. But you showed that it has at least one real root (and it's enough that $\,f(-1/2) \lt 0 \lt f(0)\,$ for that), then it must have a second real one, since non-real complex roots come in conjugate pairs.
