Solving
-3 + 6x + -2x2 = 0

Solving for variable 'x'.

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

Divide each side by '-2'.
1.5 + -3x + x2 = 0

Move the constant term to the right:

Add '-1.5' to each side of the equation.
1.5 + -3x + -1.5 + x2 = 0 + -1.5

Reorder the terms:
1.5 + -1.5 + -3x + x2 = 0 + -1.5

Combine like terms: 1.5 + -1.5 = 0.0
0.0 + -3x + x2 = 0 + -1.5
-3x + x2 = 0 + -1.5

Combine like terms: 0 + -1.5 = -1.5
-3x + x2 = -1.5

The x term is -3x.  Take half its coefficient (-1.5).
Square it (2.25) and add it to both sides.

Add '2.25' to each side of the equation.
-3x + 2.25 + x2 = -1.5 + 2.25

Reorder the terms:
2.25 + -3x + x2 = -1.5 + 2.25

Combine like terms: -1.5 + 2.25 = 0.75
2.25 + -3x + x2 = 0.75

Factor a perfect square on the left side:
(x + -1.5)(x + -1.5) = 0.75

Calculate the square root of the right side: 0.866025404

Break this problem into two subproblems by setting 
(x + -1.5) equal to 0.866025404 and -0.866025404.
