Hi there,
I have an issue using csolve/czeros.
It is giving me only one root and it is otherwise giving me infinity and minus infinity whilz there are for sure 3 complex roots.
Please help me !

Sorry, but there is no complex root for the equation you're showing us.

I dont think so.
There must be to complex conjugated solutions.

I have found by long calculations on paper
3.99+3.16*10^-4i and 3.99-3.16*10^-4i
Why doesnt it show these roots with csolve ?

BTW, thanks a lot for ur answer

1+0.8x=0, multiplying both sides by 10 we get 10+8x=0
Now 8x=-10 and finally x=-5/4
As Critor rightly said, there are no complex roots for given equation.
Best,

Hisham
