Solving for variable 'p'.

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

Divide each side by '8'.
0.125 + p + p2 = 0

Move the constant term to the right:

Add '-0.125' to each side of the equation.
0.125 + p + -0.125 + p2 = 0 + -0.125

Reorder the terms:
0.125 + -0.125 + p + p2 = 0 + -0.125

Combine like terms: 0.125 + -0.125 = 0.000
0.000 + p + p2 = 0 + -0.125
p + p2 = 0 + -0.125

Combine like terms: 0 + -0.125 = -0.125
p + p2 = -0.125

The p term is p.  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.
 + 0.25 + p2 = -0.125 + 0.25

Combine like terms:  + 0.25 = 1.25
1.25 + p2 = -0.125 + 0.25

Combine like terms: -0.125 + 0.25 = 0.125
1.25 + p2 = 0.125

Factor a perfect square on the left side:
(p + 0.5)(p + 0.5) = 0.125

Calculate the square root of the right side: 0.353553391
