Solving
6 + x + 12x2 = 0

Solving for variable 'x'.

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

Divide each side by '12'.
0.5 + 0.08333333333x + x2 = 0

Move the constant term to the right:

Add '-0.5' to each side of the equation.
0.5 + 0.08333333333x + -0.5 + x2 = 0 + -0.5

Reorder the terms:
0.5 + -0.5 + 0.08333333333x + x2 = 0 + -0.5

Combine like terms: 0.5 + -0.5 = 0.0
0.0 + 0.08333333333x + x2 = 0 + -0.5
0.08333333333x + x2 = 0 + -0.5

Combine like terms: 0 + -0.5 = -0.5
0.08333333333x + x2 = -0.5

The x term is x.  Take half its coefficient (0.5).
Square it (0.25) and add it to both sides.

Add '0.25' to each side of the equation.
0.08333333333x + 0.25 + x2 = -0.5 + 0.25

Reorder the terms:
0.25 + 0.08333333333x + x2 = -0.5 + 0.25

Combine like terms: -0.5 + 0.25 = -0.25
0.25 + 0.08333333333x + x2 = -0.25

Factor a perfect square on the left side:
(x + 0.5)(x + 0.5) = -0.25

Can't calculate square root of the right side.

The solution to this equation could not be determined.
