Solving for variable 'p'.

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

Divide each side by '8'.
1.625 + -3p + p2 = 0

Move the constant term to the right:

Add '-1.625' to each side of the equation.
1.625 + -3p + -1.625 + p2 = 0 + -1.625

Reorder the terms:
1.625 + -1.625 + -3p + p2 = 0 + -1.625

Combine like terms: 1.625 + -1.625 = 0.000
0.000 + -3p + p2 = 0 + -1.625
-3p + p2 = 0 + -1.625

Combine like terms: 0 + -1.625 = -1.625
-3p + p2 = -1.625

The p term is -3p.  Take half its coefficient (-1.5).
Square it (2.25) and add it to both sides.

Add '2.25' to each side of the equation.
-3p + 2.25 + p2 = -1.625 + 2.25

Reorder the terms:
2.25 + -3p + p2 = -1.625 + 2.25

Combine like terms: -1.625 + 2.25 = 0.625
2.25 + -3p + p2 = 0.625

Factor a perfect square on the left side:
(p + -1.5)(p + -1.5) = 0.625
