Solving for variable 'x'.

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

Divide each side by '16'.
0.0625 + -0.25x + x2 = 0

Move the constant term to the right:

Add '-0.0625' to each side of the equation.
0.0625 + -0.25x + -0.0625 + x2 = 0 + -0.0625

Reorder the terms:
0.0625 + -0.0625 + -0.25x + x2 = 0 + -0.0625

Combine like terms: 0.0625 + -0.0625 = 0.0000
0.0000 + -0.25x + x2 = 0 + -0.0625
-0.25x + x2 = 0 + -0.0625

Combine like terms: 0 + -0.0625 = -0.0625
-0.25x + x2 = -0.0625

The x term is -0.25x.  Take half its coefficient (-0.125).
Square it (0.015625) and add it to both sides.

Add '0.015625' to each side of the equation.
-0.25x + 0.015625 + x2 = -0.0625 + 0.015625

Reorder the terms:
0.015625 + -0.25x + x2 = -0.0625 + 0.015625

Combine like terms: -0.0625 + 0.015625 = -0.046875
0.015625 + -0.25x + x2 = -0.046875

Factor a perfect square on the left side:
(x + -0.125)(x + -0.125) = -0.046875

Can't calculate square root of the right side.
