Solving for variable 'x'.

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

Divide each side by '-2'.
-3 + 2.5x + x2 = 0

Move the constant term to the right:

Add '3' to each side of the equation.
-3 + 2.5x + 3 + x2 = 0 + 3

Reorder the terms:
-3 + 3 + 2.5x + x2 = 0 + 3

Combine like terms: -3 + 3 = 0
0 + 2.5x + x2 = 0 + 3
2.5x + x2 = 0 + 3

Combine like terms: 0 + 3 = 3
2.5x + x2 = 3

The x term is 2.5x.  Take half its coefficient (1.25).
Square it (1.5625) and add it to both sides.

Add '1.5625' to each side of the equation.
2.5x + 1.5625 + x2 = 3 + 1.5625

Reorder the terms:
1.5625 + 2.5x + x2 = 3 + 1.5625

Combine like terms: 3 + 1.5625 = 4.5625
1.5625 + 2.5x + x2 = 4.5625
