2 the coefficient of the squared term: 

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

Move the constant term to the right:

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

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

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

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

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.
 + 0.25 + x2 = 4.5 + 0.25

Combine like terms:  + 0.25 = 1.25
1.25 + x2 = 4.5 + 0.25

Combine like terms: 4.5 + 0.25 = 4.75
1.25 + x2 = 4.75

Factor a perfect square on the left side:
(x + 0.5)(x + 0.5) = 4.75

Calculate the square root of the right side: 2.179449472
