ANSWER
![x = \frac{ 5 - 3\sqrt{ 5} }{2} \: or \: x = \frac{ 5 +3 \sqrt{ 5} }{2}](https://tex.z-dn.net/?f=x%20%20%3D%20%20%5Cfrac%7B%205%20%20-%20%203%5Csqrt%7B%205%7D%20%7D%7B2%7D%20%20%5C%3A%20or%20%5C%3A%20x%20%20%3D%20%20%5Cfrac%7B%205%20%2B3%20%5Csqrt%7B%205%7D%20%7D%7B2%7D%20)
EXPLANATION
The given equation is
![{x}^{2} - 5x - 5 = 0](https://tex.z-dn.net/?f=%20%7Bx%7D%5E%7B2%7D%20%20-%205x%20-%205%20%3D%200)
The solution is given by the formula
![x = \frac{ - b \pm \sqrt{ {b}^{2} - 4ac} }{2a}](https://tex.z-dn.net/?f=x%20%20%3D%20%20%5Cfrac%7B%20-%20b%20%5Cpm%20%5Csqrt%7B%20%7Bb%7D%5E%7B2%7D%20%20-%204ac%7D%20%7D%7B2a%7D%20)
where a=1, b=-5, c=-5
We substitute into the formula to get;
![x = \frac{ - - 5 \pm \sqrt{ {( - 5)}^{2} - 4(1)( - 5)} }{2(1)}](https://tex.z-dn.net/?f=x%20%20%3D%20%20%5Cfrac%7B%20-%20%20-%205%20%5Cpm%20%5Csqrt%7B%20%7B%28%20-%205%29%7D%5E%7B2%7D%20%20-%204%281%29%28%20-%205%29%7D%20%7D%7B2%281%29%7D%20)
We simplify to get,
![x = \frac{ 5 \pm \sqrt{ 45} }{2}](https://tex.z-dn.net/?f=x%20%20%3D%20%20%5Cfrac%7B%205%20%5Cpm%20%5Csqrt%7B%2045%7D%20%7D%7B2%7D%20)
The solutions are:
![x = \frac{ 5 - 3\sqrt{ 5} }{2} \: or \: x = \frac{ 5 +3 \sqrt{ 5} }{2}](https://tex.z-dn.net/?f=x%20%20%3D%20%20%5Cfrac%7B%205%20%20-%20%203%5Csqrt%7B%205%7D%20%7D%7B2%7D%20%20%5C%3A%20or%20%5C%3A%20x%20%20%3D%20%20%5Cfrac%7B%205%20%2B3%20%5Csqrt%7B%205%7D%20%7D%7B2%7D%20)
The equation has no complex roots.
