The fifth power of polynomial x-9xy is decomposed into rational number range, real number range and complex number range in the following range

The fifth power of X, the fifth power of y-9xy plus a Y
=XY (the fourth power of X - the fourth power of 9y)
=XY (x square + 3Y Square) (x square - 3Y Square) rational number range
=XY (x square + 3Y Square) (x + √ 3Y) (x - √ 3Y) real number range
=XY (x + √ 3yi) (x - √ 3yi) (x + √ 3Y) (x - √ 3Y) complex range

15. How to solve polynomial equation on complex field by numerical method I have a question to ask you, that is, how to write a program to solve the polynomial equation in the complex field (for example, f (x) = A2 * x ^ 2 + A1 * x + A0 = 0). Now I use the argument principle (in short, I integrate f '(x) / F (x) on the complex plane. If there is an internal solution, the integral is not zero, otherwise it is zero), The solution is determined by continuously narrowing the integral range. However, for the higher order (greater than 10 orders), it is not enough. Is there any algorithm improvement that can improve the accuracy and speed?
