The number of negative real roots of such a polynomial equation is equal to the number of sign changes (either positive to negative or vice versa) between the coefficients of the terms of P(-x), or is less than this number by a multiple of two. Example: If we have P(x) = (x +5)(x + 1)(x – 2)(x + 2). The roots are at, -5, … ................
