Solving for variable 'x'.

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

Divide each side by '25'.
0.28 + 0.04x + x2 = 0

Move the constant term to the right:

Add '-0.28' to each side of the equation.
0.28 + 0.04x + -0.28 + x2 = 0 + -0.28

Reorder the terms:
0.28 + -0.28 + 0.04x + x2 = 0 + -0.28

Combine like terms: 0.28 + -0.28 = 0.00
0.00 + 0.04x + x2 = 0 + -0.28
0.04x + x2 = 0 + -0.28

Combine like terms: 0 + -0.28 = -0.28
0.04x + x2 = -0.28

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

Add '0.25' to each side of the equation.
0.04x + 0.25 + x2 = -0.28 + 0.25

Reorder the terms:
0.25 + 0.04x + x2 = -0.28 + 0.25

Combine like terms: -0.28 + 0.25 = -0.03
0.25 + 0.04x + x2 = -0.03

Factor a perfect square on the left side:
(x + 0.5)(x + 0.5) = -0.03

Can't calculate square root of the right side.

The solution to this equation could not be determined.
