Solving for variable 'p'.

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

Divide each side by '5'.
-2.4 + p + p2 = 0

Move the constant term to the right:

Add '2.4' to each side of the equation.
-2.4 + p + 2.4 + p2 = 0 + 2.4

Reorder the terms:
-2.4 + 2.4 + p + p2 = 0 + 2.4

Combine like terms: -2.4 + 2.4 = 0.0
0.0 + p + p2 = 0 + 2.4
p + p2 = 0 + 2.4

Combine like terms: 0 + 2.4 = 2.4
p + p2 = 2.4

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.
 + 0.25 + p2 = 2.4 + 0.25

Combine like terms:  + 0.25 = 1.25
1.25 + p2 = 2.4 + 0.25

Combine like terms: 2.4 + 0.25 = 2.65
1.25 + p2 = 2.65

Factor a perfect square on the left side:
(p + 0.5)(p + 0.5) = 2.65
