Solving
5 + -1d + d2 = 0

Solving for variable 'd'.

Begin completing the square.

Move the constant term to the right:

Add '-5' to each side of the equation.
5 + -1d + -5 + d2 = 0 + -5

Reorder the terms:
5 + -5 + -1d + d2 = 0 + -5

Combine like terms: 5 + -5 = 0
0 + -1d + d2 = 0 + -5
-1d + d2 = 0 + -5

Combine like terms: 0 + -5 = -5
-1d + d2 = -5

The d term is -1d.  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.
-1d + 0.25 + d2 = -5 + 0.25

Reorder the terms:
0.25 + -1d + d2 = -5 + 0.25

Combine like terms: -5 + 0.25 = -4.75
0.25 + -1d + d2 = -4.75

Factor a perfect square on the left side:
(d + -0.5)(d + -0.5) = -4.75
