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

Divide each side by '2'.
6.5 + -8.5p + p2 = 0

Move the constant term to the right:

Add '-6.5' to each side of the equation.
6.5 + -8.5p + -6.5 + p2 = 0 + -6.5

Reorder the terms:
6.5 + -6.5 + -8.5p + p2 = 0 + -6.5

Combine like terms: 6.5 + -6.5 = 0.0
0.0 + -8.5p + p2 = 0 + -6.5
-8.5p + p2 = 0 + -6.5

Combine like terms: 0 + -6.5 = -6.5
-8.5p + p2 = -6.5

The p term is -8.5p.  Take half its coefficient (-4.25).
Square it (18.0625) and add it to both sides.

Add '18.0625' to each side of the equation.
-8.5p + 18.0625 + p2 = -6.5 + 18.0625

Reorder the terms:
18.0625 + -8.5p + p2 = -6.5 + 18.0625

Combine like terms: -6.5 + 18.0625 = 11.5625
18.0625 + -8.5p + p2 = 11.5625
