Equations. Functions of one variable. Complex numbers,Let . be the number of changes of sign in the sequence of coefficients ., ., … , ., . in (2.8). The number of positive real roots of .(.) = 0, counting the multiplicities of the roots, is . or . minus a positive even number. If . = 1, the equation has exactly one positive real root.
