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

Divide each side by '5'.
0.2 + 1.4p + p2 = 0

Move the constant term to the right:

Add '-0.2' to each side of the equation.
0.2 + 1.4p + -0.2 + p2 = 0 + -0.2

Reorder the terms:
0.2 + -0.2 + 1.4p + p2 = 0 + -0.2

Combine like terms: 0.2 + -0.2 = 0.0
0.0 + 1.4p + p2 = 0 + -0.2
1.4p + p2 = 0 + -0.2

Combine like terms: 0 + -0.2 = -0.2
1.4p + p2 = -0.2

The p term is 1.4p.  Take half its coefficient (0.7).
Square it (0.49) and add it to both sides.

Add '0.49' to each side of the equation.
1.4p + 0.49 + p2 = -0.2 + 0.49

Reorder the terms:
0.49 + 1.4p + p2 = -0.2 + 0.49

Combine like terms: -0.2 + 0.49 = 0.29
0.49 + 1.4p + p2 = 0.29

Factor a perfect square on the left side:
(p + 0.7)(p + 0.7) = 0.29
