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 + -1.25p + p2 = 0

Move the constant term to the right:

Add '0.125' to each side of the equation.
-0.125 + -1.25p + 0.125 + p2 = 0 + 0.125

Reorder the terms:
-0.125 + 0.125 + -1.25p + p2 = 0 + 0.125

Combine like terms: -0.125 + 0.125 = 0.000
0.000 + -1.25p + p2 = 0 + 0.125
-1.25p + p2 = 0 + 0.125

Combine like terms: 0 + 0.125 = 0.125
-1.25p + p2 = 0.125

The p term is -1.25p.  Take half its coefficient (-0.625).
Square it (0.390625) and add it to both sides.

Add '0.390625' to each side of the equation.
-1.25p + 0.390625 + p2 = 0.125 + 0.390625

Reorder the terms:
0.390625 + -1.25p + p2 = 0.125 + 0.390625

Combine like terms: 0.125 + 0.390625 = 0.515625
0.390625 + -1.25p + p2 = 0.515625
