Abstract

Summary. In this article, the principal n-th root of a complex number is defined, the Vieta’s formulas for polynomial equations of degree 2, 3 and 4 are formalized. The solution of quadratic equations, the Cardan’s solution of cubic equations and the Descartes-Euler solution of quartic equations in terms of their complex coefficients are also presented [5].
