Solving for variable 'x'.

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

Divide each side by '16'.
0.8125 + 0.5x + x2 = 0

Move the constant term to the right:

Add '-0.8125' to each side of the equation.
0.8125 + 0.5x + -0.8125 + x2 = 0 + -0.8125

Reorder the terms:
0.8125 + -0.8125 + 0.5x + x2 = 0 + -0.8125

Combine like terms: 0.8125 + -0.8125 = 0.0000
0.0000 + 0.5x + x2 = 0 + -0.8125
0.5x + x2 = 0 + -0.8125

Combine like terms: 0 + -0.8125 = -0.8125
0.5x + x2 = -0.8125

The x term is 0.5x.  Take half its coefficient (0.25).
Square it (0.0625) and add it to both sides.

Add '0.0625' to each side of the equation.
0.5x + 0.0625 + x2 = -0.8125 + 0.0625

Reorder the terms:
0.0625 + 0.5x + x2 = -0.8125 + 0.0625

Combine like terms: -0.8125 + 0.0625 = -0.75
0.0625 + 0.5x + x2 = -0.75

Factor a perfect square on the left side:
(x + 0.25)(x + 0.25) = -0.75

Can't calculate square root of the right side.

The solution to this equation could not be determined.
