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

Divide each side by '10'.
-2.4 + -0.3p + p2 = 0

Move the constant term to the right:

Add '2.4' to each side of the equation.
-2.4 + -0.3p + 2.4 + p2 = 0 + 2.4

Reorder the terms:
-2.4 + 2.4 + -0.3p + p2 = 0 + 2.4

Combine like terms: -2.4 + 2.4 = 0.0
0.0 + -0.3p + p2 = 0 + 2.4
-0.3p + p2 = 0 + 2.4

Combine like terms: 0 + 2.4 = 2.4
-0.3p + p2 = 2.4

The p term is -0.3p.  Take half its coefficient (-0.15).
Square it (0.0225) and add it to both sides.

Add '0.0225' to each side of the equation.
-0.3p + 0.0225 + p2 = 2.4 + 0.0225

Reorder the terms:
0.0225 + -0.3p + p2 = 2.4 + 0.0225

Combine like terms: 2.4 + 0.0225 = 2.4225
0.0225 + -0.3p + p2 = 2.4225
