Visualising the roots of quadratic equations with complex coefficients. (English)
Aust. Sr. Math. J. 28, No. 1, 7-28 (2014).
Summary: This paper is a natural extension of the root visualisation techniques first presented by the author [ibid. 26, No. 2, 6‒20 (2012; ME 2013d.00569)] for quadratic equations with real coefficients. Consideration is now given to the familiar quadratic equation $y = ax^2 + bx + c$ in which the coefficients $a$, $b$, $c$ are generally complex, as shown explicitly in Equation (1), which is presented in the article, with the usual notation.
