-2 + 2x + -5x2 = 0

Solving for variable 'x'.

Begin completing the square.  Divide all terms by
-5 the coefficient of the squared term: 

Divide each side by '-5'.
0.4 + -0.4x + x2 = 0

Move the constant term to the right:

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

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

Combine like terms: 0.4 + -0.4 = 0.0
0.0 + -0.4x + x2 = 0 + -0.4
-0.4x + x2 = 0 + -0.4

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

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 = -0.4 + 0.04
