Solving for variable 'x'.

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

Divide each side by '2'.
11.5 + 12x + x2 = 0

Move the constant term to the right:

Add '-11.5' to each side of the equation.
11.5 + 12x + -11.5 + x2 = 0 + -11.5

Reorder the terms:
11.5 + -11.5 + 12x + x2 = 0 + -11.5

Combine like terms: 11.5 + -11.5 = 0.0
0.0 + 12x + x2 = 0 + -11.5
12x + x2 = 0 + -11.5

Combine like terms: 0 + -11.5 = -11.5
12x + x2 = -11.5

The x term is 12x.  Take half its coefficient (6).
Square it (36) and add it to both sides.

Add '36' to each side of the equation.
12x + 36 + x2 = -11.5 + 36

Reorder the terms:
36 + 12x + x2 = -11.5 + 36

Combine like terms: -11.5 + 36 = 24.5
36 + 12x + x2 = 24.5

Factor a perfect square on the left side:
(x + 6)(x + 6) = 24.5

Calculate the square root of the right side: 4.949747468

Break this problem into two subproblems by setting 
(x + 6) equal to 4.949747468 and -4.949747468.

Subproblem 1
x + 6 = 4.949747468

Simplifying
x + 6 = 4.949747468

Reorder the terms:
6 + x = 4.949747468

Solving
6 + x = 4.949747468

Solving for variable 'x'.

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

Add '-6' to each side of the equation.
6 + -6 + x = 4.949747468 + -6

Combine like terms: 6 + -6 = 0
0 + x = 4.949747468 + -6
x = 4.949747468 + -6

Combine like terms: 4.949747468 + -6 = -1.050252532
x = -1.050252532

Simplifying
x = -1.050252532

Subproblem 2
x + 6 = -4.949747468

Simplifying
x + 6 = -4.949747468

Reorder the terms:
6 + x = -4.949747468

Solving
6 + x = -4.949747468

Solving for variable 'x'.

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

Add '-6' to each side of the equation.
6 + -6 + x = -4.949747468 + -6

Combine like terms: 6 + -6 = 0
0 + x = -4.949747468 + -6
x = -4.949747468 + -6

Combine like terms: -4.949747468 + -6 = -10.949747468
x = -10.949747468

Simplifying
x = -10.949747468

Solution
