Solving for variable 'x'.

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

Divide each side by '4'.
18.75 + 0.25x + x2 = 0

Move the constant term to the right:

Add '-18.75' to each side of the equation.
18.75 + 0.25x + -18.75 + x2 = 0 + -18.75

Reorder the terms:
18.75 + -18.75 + 0.25x + x2 = 0 + -18.75

Combine like terms: 18.75 + -18.75 = 0.00
0.00 + 0.25x + x2 = 0 + -18.75
0.25x + x2 = 0 + -18.75

Combine like terms: 0 + -18.75 = -18.75
0.25x + x2 = -18.75

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.
0.25x + 0.25 + x2 = -18.75 + 0.25
