WebGräffe is best remembered for his "root-squaring" method of numerical solution of algebraic equations, developed to answer a prize question posed by the Berlin Academy of Sciences. This was not his first numerical work on equations for he had published Beweis eines Satzes aus der Theorie der numerischen Gleichungen Ⓣ in Crelle 's Journal in 1833. WebGraeffe’s root squaring method for soling nonv linear algebraic equations is - a well known classical method. It was developed by C. H. Graeffe in 1837. Its explanation, uses and avantages are d available inmany treatises and literatures. Hutchinson [3] d e-scribed the method to be very useful in aerodynamics and in electrical analysis.

Webroots of the equation are calculated. It is found that the odd degree equations set like x3 x O, x 7 .x5 (2.1) etc. cannot be solved by the Graeffe's root squaring method manually as well What is today often called the Graeffe Root-Squaring method was discovered independently by Dandelin, Lobacevskii, and Graeffe in 1826, 1834 and 1837.
