Solving for variable 'x'.

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

Divide each side by '-2'.
5 + -7.5x + x2 = 0

Move the constant term to the right:

Add '-5' to each side of the equation.
5 + -7.5x + -5 + x2 = 0 + -5

Reorder the terms:
5 + -5 + -7.5x + x2 = 0 + -5

Combine like terms: 5 + -5 = 0
0 + -7.5x + x2 = 0 + -5
-7.5x + x2 = 0 + -5

Combine like terms: 0 + -5 = -5
-7.5x + x2 = -5

The x term is -7.5x.  Take half its coefficient (-3.75).
Square it (14.0625) and add it to both sides.

Add '14.0625' to each side of the equation.
-7.5x + 14.0625 + x2 = -5 + 14.0625

Reorder the terms:
14.0625 + -7.5x + x2 = -5 + 14.0625

Combine like terms: -5 + 14.0625 = 9.0625
14.0625 + -7.5x + x2 = 9.0625
