Begin completing the square.  Divide all terms by
12 the coefficient of the squared term: 

Divide each side by '12'.
-0.08333333333 + 2x + x2 = 0

Move the constant term to the right:

Add '0.08333333333' to each side of the equation.
-0.08333333333 + 2x + 0.08333333333 + x2 = 0 + 0.08333333333

Reorder the terms:
-0.08333333333 + 0.08333333333 + 2x + x2 = 0 + 0.08333333333

Combine like terms: -0.08333333333 + 0.08333333333 = 0.00000000000
0.00000000000 + 2x + x2 = 0 + 0.08333333333
2x + x2 = 0 + 0.08333333333

Combine like terms: 0 + 0.08333333333 = 0.08333333333
2x + x2 = 0.08333333333

The x term is 2x.  Take half its coefficient (1).
Square it (1) and add it to both sides.

Add '1' to each side of the equation.
2x + 1 + x2 = 0.08333333333 + 1

Reorder the terms:
1 + 2x + x2 = 0.08333333333 + 1

Combine like terms: 0.08333333333 + 1 = 1.08333333333
1 + 2x + x2 = 1.08333333333

Factor a perfect square on the left side:
(x + 1)(x + 1) = 1.08333333333

Calculate the square root of the right side: 1.040833

Break this problem into two subproblems by setting 
(x + 1) equal to 1.040833 and -1.040833.

Subproblem 1
x + 1 = 1.040833

Simplifying
x + 1 = 1.040833

Reorder the terms:
1 + x = 1.040833

Solving
1 + x = 1.040833

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-1' to each side of the equation.
1 + -1 + x = 1.040833 + -1

Combine like terms: 1 + -1 = 0
0 + x = 1.040833 + -1
x = 1.040833 + -1

Combine like terms: 1.040833 + -1 = 0.040833
x = 0.040833

Simplifying
x = 0.040833

Subproblem 2
x + 1 = -1.040833

Simplifying
x + 1 = -1.040833

Reorder the terms:
1 + x = -1.040833

Solving
1 + x = -1.040833

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-1' to each side of the equation.
1 + -1 + x = -1.040833 + -1

Combine like terms: 1 + -1 = 0
0 + x = -1.040833 + -1
x = -1.040833 + -1
