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

Divide each side by '2'.
3.5 + 0.5p + p2 = 0

Move the constant term to the right:

Add '-3.5' to each side of the equation.
3.5 + 0.5p + -3.5 + p2 = 0 + -3.5

Reorder the terms:
3.5 + -3.5 + 0.5p + p2 = 0 + -3.5

Combine like terms: 3.5 + -3.5 = 0.0
0.0 + 0.5p + p2 = 0 + -3.5
0.5p + p2 = 0 + -3.5

Combine like terms: 0 + -3.5 = -3.5
0.5p + p2 = -3.5

The p term is p.  Take half its coefficient (0.5).
Square it (0.25) and add it to both sides.

Add '0.25' to each side of the equation.
0.5p + 0.25 + p2 = -3.5 + 0.25
