Solving for variable 'p'.

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

Divide each side by '10'.
0.2 + -1.1p + p2 = 0

Move the constant term to the right:

Add '-0.2' to each side of the equation.
0.2 + -1.1p + -0.2 + p2 = 0 + -0.2

Reorder the terms:
0.2 + -0.2 + -1.1p + p2 = 0 + -0.2

Combine like terms: 0.2 + -0.2 = 0.0
0.0 + -1.1p + p2 = 0 + -0.2
-1.1p + p2 = 0 + -0.2

Combine like terms: 0 + -0.2 = -0.2
-1.1p + p2 = -0.2

The p term is -1.1p.  Take half its coefficient (-0.55).
Square it (0.3025) and add it to both sides.

Add '0.3025' to each side of the equation.
-1.1p + 0.3025 + p2 = -0.2 + 0.3025

Reorder the terms:
0.3025 + -1.1p + p2 = -0.2 + 0.3025

Combine like terms: -0.2 + 0.3025 = 0.1025
0.3025 + -1.1p + p2 = 0.1025

Factor a perfect square on the left side:
(p + -0.55)(p + -0.55) = 0.1025

Calculate the square root of the right side: 0.320156212
