A program is outlined for solving a polynominal a(x) of n = 2m degree on the 610 IBM electronic computer (max. n = 18). Using the Bairstow iterative process the approximate quadratic factor is determined. The degree of polynomlal is successively lowered. Thus m quadratic polynomials are found. Each quadratic polynomial deduced from a polynomial of lowered degree is tested in the given polynomial a(x) for reduction of rounding errors. The roots of quadratic polynomials are defined by the usual formula. (auth)
