Answer:
[tex]x=8+3i,\:x=8-3i[/tex]
Step-by-step explanation:
Use the quadratic formula
[tex]x_{1,\:2}=\frac{-\left(-16\right)\pm \sqrt{\left(-16\right)^2-4\cdot \:1\cdot \:73}}{2\cdot \:1}[/tex]
Separate the solutions:
[tex]x_1=\frac{-\left(-16\right)+6i}{2\cdot \:1},\:x_2=\frac{-\left(-16\right)-6i}{2\cdot \:1}[/tex]
Other answers:
[tex]x_1 =8+3i\\x_2=8-3i[/tex]
