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

Divide each side by '-5'.
3 + -4.2p + p2 = 0

Move the constant term to the right:

Add '-3' to each side of the equation.
3 + -4.2p + -3 + p2 = 0 + -3

Reorder the terms:
3 + -3 + -4.2p + p2 = 0 + -3

Combine like terms: 3 + -3 = 0
0 + -4.2p + p2 = 0 + -3
-4.2p + p2 = 0 + -3

Combine like terms: 0 + -3 = -3
-4.2p + p2 = -3

The p term is -4.2p.  Take half its coefficient (-2.1).
Square it (4.41) and add it to both sides.

Add '4.41' to each side of the equation.
-4.2p + 4.41 + p2 = -3 + 4.41

Reorder the terms:
4.41 + -4.2p + p2 = -3 + 4.41

Combine like terms: -3 + 4.41 = 1.41
4.41 + -4.2p + p2 = 1.41
