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

Divide each side by '4'.
-0.75 + -1.5x + x2 = 0

Move the constant term to the right:

Add '0.75' to each side of the equation.
-0.75 + -1.5x + 0.75 + x2 = 0 + 0.75

Reorder the terms:
-0.75 + 0.75 + -1.5x + x2 = 0 + 0.75

Combine like terms: -0.75 + 0.75 = 0.00
0.00 + -1.5x + x2 = 0 + 0.75
-1.5x + x2 = 0 + 0.75

Combine like terms: 0 + 0.75 = 0.75
-1.5x + x2 = 0.75

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