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

Divide each side by '-4'.
-0.25 + -1.5x + x2 = 0

Move the constant term to the right:

Add '0.25' to each side of the equation.
-0.25 + -1.5x + 0.25 + x2 = 0 + 0.25

Reorder the terms:
-0.25 + 0.25 + -1.5x + x2 = 0 + 0.25

Combine like terms: -0.25 + 0.25 = 0.00
0.00 + -1.5x + x2 = 0 + 0.25
-1.5x + x2 = 0 + 0.25

Combine like terms: 0 + 0.25 = 0.25
-1.5x + x2 = 0.25

The x term is -1.5x.  Take half its coefficient (-0.75).
