Witryna6 lis 2024 · When applying Descartes’ rule, we count roots of multiplicity k as k roots. 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.
