Solving for variable 'x'.

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

Divide each side by '25'.
-2 + -0.04x + x2 = 0

Move the constant term to the right:

Add '2' to each side of the equation.
-2 + -0.04x + 2 + x2 = 0 + 2

Reorder the terms:
-2 + 2 + -0.04x + x2 = 0 + 2

Combine like terms: -2 + 2 = 0
0 + -0.04x + x2 = 0 + 2
-0.04x + x2 = 0 + 2

Combine like terms: 0 + 2 = 2
-0.04x + x2 = 2

The x term is -0.04x.  Take half its coefficient (-0.02).
Square it (0.0004) and add it to both sides.

Add '0.0004' to each side of the equation.
-0.04x + 0.0004 + x2 = 2 + 0.0004

Reorder the terms:
0.0004 + -0.04x + x2 = 2 + 0.0004

Combine like terms: 2 + 0.0004 = 2.0004
0.0004 + -0.04x + x2 = 2.0004
