Solving for variable 'p'.

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

Divide each side by '2'.
-2 + 2.5p + p2 = 0

Move the constant term to the right:

Add '2' to each side of the equation.
-2 + 2.5p + 2 + p2 = 0 + 2

Reorder the terms:
-2 + 2 + 2.5p + p2 = 0 + 2

Combine like terms: -2 + 2 = 0
0 + 2.5p + p2 = 0 + 2
2.5p + p2 = 0 + 2

Combine like terms: 0 + 2 = 2
2.5p + p2 = 2

The p term is 2.5p.  Take half its coefficient (1.25).
Square it (1.5625) and add it to both sides.

Add '1.5625' to each side of the equation.
2.5p + 1.5625 + p2 = 2 + 1.5625

Reorder the terms:
1.5625 + 2.5p + p2 = 2 + 1.5625

Combine like terms: 2 + 1.5625 = 3.5625
1.5625 + 2.5p + p2 = 3.5625
