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

Divide each side by '25'.
0.12 + -0.4x + x2 = 0

Move the constant term to the right:

Add '-0.12' to each side of the equation.
0.12 + -0.4x + -0.12 + x2 = 0 + -0.12

Reorder the terms:
0.12 + -0.12 + -0.4x + x2 = 0 + -0.12

Combine like terms: 0.12 + -0.12 = 0.00
0.00 + -0.4x + x2 = 0 + -0.12
-0.4x + x2 = 0 + -0.12

Combine like terms: 0 + -0.12 = -0.12
-0.4x + x2 = -0.12

The x term is -0.4x.  Take half its coefficient (-0.2).
Square it (0.04) and add it to both sides.

Add '0.04' to each side of the equation.
-0.4x + 0.04 + x2 = -0.12 + 0.04

Reorder the terms:
0.04 + -0.4x + x2 = -0.12 + 0.04

Combine like terms: -0.12 + 0.04 = -0.08
0.04 + -0.4x + x2 = -0.08

Factor a perfect square on the left side:
(x + -0.2)(x + -0.2) = -0.08

Can't calculate square root of the right side.

The solution to this equation could not be determined.
