Solving for variable 'x'.

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

Divide each side by '25'.
0.16 + 0.4x + x2 = 0

Move the constant term to the right:

Add '-0.16' to each side of the equation.
0.16 + 0.4x + -0.16 + x2 = 0 + -0.16

Reorder the terms:
0.16 + -0.16 + 0.4x + x2 = 0 + -0.16

Combine like terms: 0.16 + -0.16 = 0.00
0.00 + 0.4x + x2 = 0 + -0.16
0.4x + x2 = 0 + -0.16

Combine like terms: 0 + -0.16 = -0.16
0.4x + x2 = -0.16

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 = -0.16 + 0.04

Reorder the terms:
0.04 + 0.4x + x2 = -0.16 + 0.04

Combine like terms: -0.16 + 0.04 = -0.12
0.04 + 0.4x + x2 = -0.12

Factor a perfect square on the left side:
(x + 0.2)(x + 0.2) = -0.12

Can't calculate square root of the right side.

The solution to this equation could not be determined.
