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

Divide each side by '2'.
1.5 + 12.5p + p2 = 0

Move the constant term to the right:

Add '-1.5' to each side of the equation.
1.5 + 12.5p + -1.5 + p2 = 0 + -1.5

Reorder the terms:
1.5 + -1.5 + 12.5p + p2 = 0 + -1.5

Combine like terms: 1.5 + -1.5 = 0.0
0.0 + 12.5p + p2 = 0 + -1.5
12.5p + p2 = 0 + -1.5

Combine like terms: 0 + -1.5 = -1.5
12.5p + p2 = -1.5

The p term is 12.5p.  Take half its coefficient (6.25).
Square it (39.0625) and add it to both sides.

Add '39.0625' to each side of the equation.
12.5p + 39.0625 + p2 = -1.5 + 39.0625

Reorder the terms:
39.0625 + 12.5p + p2 = -1.5 + 39.0625

Combine like terms: -1.5 + 39.0625 = 37.5625
