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

Divide each side by '-4'.
1.25 + -0.5x + x2 = 0

Move the constant term to the right:

Add '-1.25' to each side of the equation.
1.25 + -0.5x + -1.25 + x2 = 0 + -1.25

Reorder the terms:
1.25 + -1.25 + -0.5x + x2 = 0 + -1.25

Combine like terms: 1.25 + -1.25 = 0.00
0.00 + -0.5x + x2 = 0 + -1.25
-0.5x + x2 = 0 + -1.25

Combine like terms: 0 + -1.25 = -1.25
-0.5x + x2 = -1.25

The x term is -0.5x.  Take half its coefficient (-0.25).
Square it (0.0625) and add it to both sides.

Add '0.0625' to each side of the equation.
-0.5x + 0.0625 + x2 = -1.25 + 0.0625

Reorder the terms:
0.0625 + -0.5x + x2 = -1.25 + 0.0625

Combine like terms: -1.25 + 0.0625 = -1.1875
0.0625 + -0.5x + x2 = -1.1875

Factor a perfect square on the left side:
(x + -0.25)(x + -0.25) = -1.1875

Can't calculate square root of the right side.
