Solving for variable 'd'.

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

Divide each side by '16'.
-0.1875 + 0.25d + d2 = 0

Move the constant term to the right:

Add '0.1875' to each side of the equation.
-0.1875 + 0.25d + 0.1875 + d2 = 0 + 0.1875

Reorder the terms:
-0.1875 + 0.1875 + 0.25d + d2 = 0 + 0.1875

Combine like terms: -0.1875 + 0.1875 = 0.0000
0.0000 + 0.25d + d2 = 0 + 0.1875
0.25d + d2 = 0 + 0.1875

Combine like terms: 0 + 0.1875 = 0.1875
0.25d + d2 = 0.1875

The d term is 0.25d.  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.
0.25d + 0.015625 + d2 = 0.1875 + 0.015625

Reorder the terms:
0.015625 + 0.25d + d2 = 0.1875 + 0.015625

Combine like terms: 0.1875 + 0.015625 = 0.203125
0.015625 + 0.25d + d2 = 0.203125

Factor a perfect square on the left side:
(d + 0.125)(d + 0.125) = 0.203125
