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 + 1.5x + x2 = 0

Move the constant term to the right:

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

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

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

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

The x term is 1.5x.  Take half its coefficient (0.75).
Square it (0.5625) and add it to both sides.

Add '0.5625' to each side of the equation.
1.5x + 0.5625 + x2 = -1.5 + 0.5625

Reorder the terms:
0.5625 + 1.5x + x2 = -1.5 + 0.5625

Combine like terms: -1.5 + 0.5625 = -0.9375
0.5625 + 1.5x + x2 = -0.9375

Factor a perfect square on the left side:
(x + 0.75)(x + 0.75) = -0.9375

Can't calculate square root of the right side.

The solution to this equation could not be determined.
