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 + 1.2x + x2 = 0

Move the constant term to the right:

Add '-0.16' to each side of the equation.
0.16 + 1.2x + -0.16 + x2 = 0 + -0.16

Reorder the terms:
0.16 + -0.16 + 1.2x + x2 = 0 + -0.16

Combine like terms: 0.16 + -0.16 = 0.00
0.00 + 1.2x + x2 = 0 + -0.16
1.2x + x2 = 0 + -0.16

Combine like terms: 0 + -0.16 = -0.16
1.2x + x2 = -0.16

The x term is 1.2x.  Take half its coefficient (0.6).
Square it (0.36) and add it to both sides.

Add '0.36' to each side of the equation.
1.2x + 0.36 + x2 = -0.16 + 0.36

Reorder the terms:
0.36 + 1.2x + x2 = -0.16 + 0.36

Combine like terms: -0.16 + 0.36 = 0.2
0.36 + 1.2x + x2 = 0.2

Factor a perfect square on the left side:
(x + 0.6)(x + 0.6) = 0.2
