Answer:
Option 1) ![x=-2+i\sqrt{2}](https://tex.z-dn.net/?f=x%3D-2%2Bi%5Csqrt%7B2%7D)
Step-by-step explanation:
we know that
The formula to solve a quadratic equation of the form
is equal to
![x=\frac{-b\pm\sqrt{b^{2}-4ac}} {2a}](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B-b%5Cpm%5Csqrt%7Bb%5E%7B2%7D-4ac%7D%7D%20%7B2a%7D)
in this problem we have
so
substitute in the formula
![x=\frac{-4\pm\sqrt{4^{2}-4(1)(6)}} {2(1)}](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B-4%5Cpm%5Csqrt%7B4%5E%7B2%7D-4%281%29%286%29%7D%7D%20%7B2%281%29%7D)
![x=\frac{-4\pm\sqrt{-8}} {2}](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B-4%5Cpm%5Csqrt%7B-8%7D%7D%20%7B2%7D)
Remember that
![i=\sqrt{-1}](https://tex.z-dn.net/?f=i%3D%5Csqrt%7B-1%7D)
so
![x=\frac{-4\pm i\sqrt{8}} {2}](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B-4%5Cpm%20i%5Csqrt%7B8%7D%7D%20%7B2%7D)
![x=\frac{-4\pm2i\sqrt{2}} {2}](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B-4%5Cpm2i%5Csqrt%7B2%7D%7D%20%7B2%7D)
![x=-2\pm i\sqrt{2}](https://tex.z-dn.net/?f=x%3D-2%5Cpm%20i%5Csqrt%7B2%7D)
The solutions are
![x=-2+i\sqrt{2}](https://tex.z-dn.net/?f=x%3D-2%2Bi%5Csqrt%7B2%7D)
and
![x=-2-i\sqrt{2}](https://tex.z-dn.net/?f=x%3D-2-i%5Csqrt%7B2%7D)
