Answer:
x = -0.17 and x = -5.83
Step-by-step explanation:
We are asked to solve the quadratic equation
![x^2+6\,x+1=0](https://tex.z-dn.net/?f=x%5E2%2B6%5C%2Cx%2B1%3D0)
We use the quadratic formula using a = 1, b = 6 and c = 1
for a general quadratic equation of the form: ![ax^2+bx+c=0](https://tex.z-dn.net/?f=ax%5E2%2Bbx%2Bc%3D0)
Then, the solutions are given by;
![x=\frac{-6+/-\sqrt{36-4\,(1)\,(1)} }{2} =\frac{-6+/-\sqrt{32} }{2}](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B-6%2B%2F-%5Csqrt%7B36-4%5C%2C%281%29%5C%2C%281%29%7D%20%7D%7B2%7D%20%3D%5Cfrac%7B-6%2B%2F-%5Csqrt%7B32%7D%20%7D%7B2%7D)
which produces the two following answers (rounded to two decimals):
x = -0.17 and x = -5.83
