What is the Descartes Rule of Signs?
The Descartes Rule of Signs is a theorem in algebra that provides a straightforward method for determining the number of positive and negative real roots of a polynomial. The rule states that the number of positive real roots of a polynomial function is either equal to the number of sign changes between consecutive non-zero coefficients or less than that by an even integer. Conversely, for negative roots, one can evaluate the polynomial using the variable substitution \(x\) with \(-x\) and apply the same principle.
