How do I solve this complex equation?
显示 更早的评论
I have to solve the equation 4Z^4-11Z^2+7-3i=0, where Z is a complex number
My thoughts are to do this:
p=[4,0,-11,0,7-3i]
roots(p)
However, the answer I get is different from the actual answer, which is
2.4849+0.1552i
0.9924-0.2898i
-0.7273+0.1347i
Any help is appreciated!

I believe you are getting the correct answer
% method 1
syms Z
eqn=4*Z^4-11*Z^2+7-3i==0;
Root=vpasolve(eqn)
% method 2
roots(sym2poly(eqn))
