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

Divide each side by '-4'.
-0.75 + 2.5x + x2 = 0

Move the constant term to the right:

Add '0.75' to each side of the equation.
-0.75 + 2.5x + 0.75 + x2 = 0 + 0.75

Reorder the terms:
-0.75 + 0.75 + 2.5x + x2 = 0 + 0.75

Combine like terms: -0.75 + 0.75 = 0.00
0.00 + 2.5x + x2 = 0 + 0.75
2.5x + x2 = 0 + 0.75

Combine like terms: 0 + 0.75 = 0.75
2.5x + x2 = 0.75

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 = 0.75 + 1.5625

Reorder the terms:
1.5625 + 2.5x + x2 = 0.75 + 1.5625

Combine like terms: 0.75 + 1.5625 = 2.3125
1.5625 + 2.5x + x2 = 2.3125
