$$x_{1} = - \frac{\left(\operatorname{re}{\left(a\right)} - 7\right)^{2}}{2} - i \left(\operatorname{re}{\left(a\right)} - 7\right) \operatorname{im}{\left(a\right)} + \frac{\left(\operatorname{im}{\left(a\right)}\right)^{2}}{2} + \frac{1}{2}$$
x1 = -(re(a) - 7)^2/2 - i*(re(a) - 7)*im(a) + im(a)^2/2 + 1/2
