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

Divide each side by '14'.
0.07142857143 + -0.5d + d2 = 0

Move the constant term to the right:

Add '-0.07142857143' to each side of the equation.
0.07142857143 + -0.5d + -0.07142857143 + d2 = 0 + -0.07142857143

Reorder the terms:
0.07142857143 + -0.07142857143 + -0.5d + d2 = 0 + -0.07142857143

Combine like terms: 0.07142857143 + -0.07142857143 = 0.00000000000
0.00000000000 + -0.5d + d2 = 0 + -0.07142857143
-0.5d + d2 = 0 + -0.07142857143

Combine like terms: 0 + -0.07142857143 = -0.07142857143
-0.5d + d2 = -0.07142857143

The d term is -0.5d.  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.
-0.5d + 0.0625 + d2 = -0.07142857143 + 0.0625

Reorder the terms:
0.0625 + -0.5d + d2 = -0.07142857143 + 0.0625

Combine like terms: -0.07142857143 + 0.0625 = -0.00892857143
0.0625 + -0.5d + d2 = -0.00892857143

Factor a perfect square on the left side:
(d + -0.25)(d + -0.25) = -0.00892857143

Can't calculate square root of the right side.
