25 the coefficient of the squared term: 

Divide each side by '25'.
-0.28 + -0.12x + x2 = 0

Move the constant term to the right:

Add '0.28' to each side of the equation.
-0.28 + -0.12x + 0.28 + x2 = 0 + 0.28

Reorder the terms:
-0.28 + 0.28 + -0.12x + x2 = 0 + 0.28

Combine like terms: -0.28 + 0.28 = 0.00
0.00 + -0.12x + x2 = 0 + 0.28
-0.12x + x2 = 0 + 0.28

Combine like terms: 0 + 0.28 = 0.28
-0.12x + x2 = 0.28

The x term is -0.12x.  Take half its coefficient (-0.06).
Square it (0.0036) and add it to both sides.

Add '0.0036' to each side of the equation.
-0.12x + 0.0036 + x2 = 0.28 + 0.0036

Reorder the terms:
0.0036 + -0.12x + x2 = 0.28 + 0.0036

Combine like terms: 0.28 + 0.0036 = 0.2836
