Solving for variable 'x'.

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

Divide each side by '16'.
0.3125 + x + x2 = 0

Move the constant term to the right:

Add '-0.3125' to each side of the equation.
0.3125 + x + -0.3125 + x2 = 0 + -0.3125

Reorder the terms:
0.3125 + -0.3125 + x + x2 = 0 + -0.3125

Combine like terms: 0.3125 + -0.3125 = 0.0000
0.0000 + x + x2 = 0 + -0.3125
x + x2 = 0 + -0.3125

Combine like terms: 0 + -0.3125 = -0.3125
x + x2 = -0.3125

The x term is x.  Take half its coefficient (0.5).
Square it (0.25) and add it to both sides.

Add '0.25' to each side of the equation.
 + 0.25 + x2 = -0.3125 + 0.25

Combine like terms:  + 0.25 = 1.25
1.25 + x2 = -0.3125 + 0.25

Combine like terms: -0.3125 + 0.25 = -0.0625
1.25 + x2 = -0.0625

Factor a perfect square on the left side:
(x + 0.5)(x + 0.5) = -0.0625

Can't calculate square root of the right side.
