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

Divide each side by '2'.
4.5 + 0.5x + x2 = 0

Move the constant term to the right:

Add '-4.5' to each side of the equation.
4.5 + 0.5x + -4.5 + x2 = 0 + -4.5

Reorder the terms:
4.5 + -4.5 + 0.5x + x2 = 0 + -4.5

Combine like terms: 4.5 + -4.5 = 0.0
0.0 + 0.5x + x2 = 0 + -4.5
0.5x + x2 = 0 + -4.5

Combine like terms: 0 + -4.5 = -4.5
0.5x + x2 = -4.5

The x term is 0.5x.  Take half its coefficient (0.25).
Square it (0.0625) and add it to both sides.

Add '0.0625' to each side of the equation.
0.5x + 0.0625 + x2 = -4.5 + 0.0625

Reorder the terms:
0.0625 + 0.5x + x2 = -4.5 + 0.0625

Combine like terms: -4.5 + 0.0625 = -4.4375
0.0625 + 0.5x + x2 = -4.4375

Factor a perfect square on the left side:
(x + 0.25)(x + 0.25) = -4.4375

Can't calculate square root of the right side.

The solution to this equation could not be determined.
