Web3.43 graeffe’s root-squaring method This method has a great advantage over the other methods in that it does not require prior information about the approximate values, etc., of the roots. It is applicable to polynomial equations only and is capable of giving all the roots. WebSince f(2.00) = 0, f(1.0218) = 0 and f(0.978) = 0, the signs of the roots 2.00, 1.0128 and 0.978 are all positive. 4. Find the root of x 3 - 6x 2 + 11x - 6 = 0

There are other methods, though not discussed in this paper, 1. 2 that are 'self starting' or 'global' in the manner in which they approximate the roots to transcendental equations. These methods
In mathematics, Graeffe's method or Dandelin–Lobachesky–Graeffe method is an algorithm for finding all of the roots of a polynomial. It was developed independently by Germinal Pierre Dandelin in 1826 and Lobachevsky in 1834. In 1837 Karl Heinrich Gräffe also discovered the principal idea of the method. The method separates the roots of a polynomial by squaring them repeatedly. This squaring of the roots is done implicitly, that is, only working on the coefficients …
