NARA [144]

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

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

Then, the solutions are given by;

x=\frac{-6+/-\sqrt{36-4\,(1)\,(1)} }{2} =\frac{-6+/-\sqrt{32} }{2}

which produces the two following answers (rounded to two decimals):

x = -0.17   and    x = -5.83

Rename as a mixed number in simplest form. 15 22/20
Semenov [28]
16 1/10
Because you have 15 and then for 22/20 it is a improper fraction so take 20 away from it to get 2/10 then add 1 to 15 for 16 and then simplify 2/20 to 1/10
