Solving for variable 'x'.

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

Divide each side by '50'.
-0.08 + 0.38x + x2 = 0

Move the constant term to the right:

Add '0.08' to each side of the equation.
-0.08 + 0.38x + 0.08 + x2 = 0 + 0.08

Reorder the terms:
-0.08 + 0.08 + 0.38x + x2 = 0 + 0.08

Combine like terms: -0.08 + 0.08 = 0.00
0.00 + 0.38x + x2 = 0 + 0.08
0.38x + x2 = 0 + 0.08

Combine like terms: 0 + 0.08 = 0.08
0.38x + x2 = 0.08

The x term is 0.38x.  Take half its coefficient (0.19).
Square it (0.0361) and add it to both sides.

Add '0.0361' to each side of the equation.
0.38x + 0.0361 + x2 = 0.08 + 0.0361

Reorder the terms:
0.0361 + 0.38x + x2 = 0.08 + 0.0361

Combine like terms: 0.08 + 0.0361 = 0.1161
0.0361 + 0.38x + x2 = 0.1161

Factor a perfect square on the left side:
(x + 0.19)(x + 0.19) = 0.1161
