\left\{ \begin{array} { l } { a + b + 4 = 0 } \\ { ( 1 + e + \frac { 1 } { 2 } b ) ^ { 2 } - 4 \frac { 5 } { 4 } ( 1 + b ) = 0 } \end{array} \right.
Solve for a, b
a=\frac{i\sqrt{168e-357}}{2}+2e-\frac{25}{2}\approx -7.063436343+4.991776918i\text{, }b=-\frac{i\sqrt{168e-357}}{2}+\frac{17}{2}-2e\approx 3.063436343-4.991776918i
a=-\frac{i\sqrt{168e-357}}{2}+2e-\frac{25}{2}\approx -7.063436343-4.991776918i\text{, }b=\frac{i\sqrt{168e-357}}{2}+\frac{17}{2}-2e\approx 3.063436343+4.991776918i
