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 + 1.5p + p2 = 0

Move the constant term to the right:

Add '0.125' to each side of the equation.
-0.125 + 1.5p + 0.125 + p2 = 0 + 0.125

Reorder the terms:
-0.125 + 0.125 + 1.5p + p2 = 0 + 0.125

Combine like terms: -0.125 + 0.125 = 0.000
0.000 + 1.5p + p2 = 0 + 0.125
1.5p + p2 = 0 + 0.125

Combine like terms: 0 + 0.125 = 0.125
1.5p + p2 = 0.125

The p term is 1.5p.  Take half its coefficient (0.75).
Square it (0.5625) and add it to both sides.

Add '0.5625' to each side of the equation.
1.5p + 0.5625 + p2 = 0.125 + 0.5625

Reorder the terms:
0.5625 + 1.5p + p2 = 0.125 + 0.5625

Combine like terms: 0.125 + 0.5625 = 0.6875
0.5625 + 1.5p + p2 = 0.6875
