Question 932861
You might be hoping to use the two formulas for x as ROOTS of a quadratic equation.  Form the factors of the quadratic expression and fully multiply these factors.  


You might really be starting with this:
{{{x=2+5i}}} or {{{x=2-5i}}};
You had a "x" present which should not have been written there.


Your equation would start as   {{{(x-(2+5i))(x-(2-5i))=0}}}.
Continue from that.
