Hi everyone
I want to solve this equation by multiplying these variables with imaginary numbers and get clear result with s variable and output is in some weird form. What's wrong?
My code below .
clc;
clear;
s1 = 133.9457 + 253.416i
s2 = 133.9457 - 253.416i
s3 = 1339.457
syms s
x = solve(0.00017493*(s-s1)*(s-s2)*(s-s3))
Thanks in advance

s1 = 133.9457 + 253.416i;
s2 = 133.9457 - 253.416i;
s3 = 1339.457;
syms s
x_exactly = solve(0.00017493*(s-s1)*(s-s2)*(s-s3))
x_numeric = double(x_exactly)
