Let I be a set of functions : D = {f,(x) = 589\\ -bj 24 + bir + 20 1bj = -4, n EN). Let A be the set of the roots with a positive imaginary part of every functions of I : A = {y E CO = f,(y), Im(y) 2 0, f, ED}. Find the sum of every elements of A. Round both the real and the imaginary part to the nearest integer
