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

Divide each side by '25'.
-0.12 + 0.56x + x2 = 0

Move the constant term to the right:

Add '0.12' to each side of the equation.
-0.12 + 0.56x + 0.12 + x2 = 0 + 0.12

Reorder the terms:
-0.12 + 0.12 + 0.56x + x2 = 0 + 0.12

Combine like terms: -0.12 + 0.12 = 0.00
0.00 + 0.56x + x2 = 0 + 0.12
0.56x + x2 = 0 + 0.12

Combine like terms: 0 + 0.12 = 0.12
0.56x + x2 = 0.12

The x term is 0.56x.  Take half its coefficient (0.28).
Square it (0.0784) and add it to both sides.

Add '0.0784' to each side of the equation.
0.56x + 0.0784 + x2 = 0.12 + 0.0784

Reorder the terms:
0.0784 + 0.56x + x2 = 0.12 + 0.0784

Combine like terms: 0.12 + 0.0784 = 0.1984
0.0784 + 0.56x + x2 = 0.1984

Factor a perfect square on the left side:
(x + 0.28)(x + 0.28) = 0.1984
