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 + 2x + x2 = 0

Move the constant term to the right:

Add '-1.5' to each side of the equation.
1.5 + 2x + -1.5 + x2 = 0 + -1.5

Reorder the terms:
1.5 + -1.5 + 2x + x2 = 0 + -1.5

Combine like terms: 1.5 + -1.5 = 0.0
0.0 + 2x + x2 = 0 + -1.5
2x + x2 = 0 + -1.5

Combine like terms: 0 + -1.5 = -1.5
2x + x2 = -1.5

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