Question 1197613
If you were given that number is a root of an equation then if degree 2 equation, you must also have
{{{-3+5i}}} as the other root.  


{{{(x-(-3-5i))(x-(-3+5i))=0}}}

{{{(x+3+5i)(x+3-5i)=0}}}

{{{((x+3)+5i)((x+3)-5i)=0}}}

{{{(x+3)^2-(5i)^2=0}}}

{{{x^2+6x+9-25(-1)=0}}}

{{{x^2+6x+9+25=0}}}

{{{x^2+6x+34=0}}}---------maybe you were looking for this.
