Solving for variable 'p'.

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

Divide each side by '400'.
0.0025 + -0.9p2 + p4 = 0

Move the constant term to the right:

Add '-0.0025' to each side of the equation.
0.0025 + -0.9p2 + -0.0025 + p4 = 0 + -0.0025

Reorder the terms:
0.0025 + -0.0025 + -0.9p2 + p4 = 0 + -0.0025

Combine like terms: 0.0025 + -0.0025 = 0.0000
0.0000 + -0.9p2 + p4 = 0 + -0.0025
-0.9p2 + p4 = 0 + -0.0025

Combine like terms: 0 + -0.0025 = -0.0025
-0.9p2 + p4 = -0.0025

The p term is -0.9p2.  Take half its coefficient (-0.45).
Square it (0.2025) and add it to both sides.

Add '0.2025' to each side of the equation.
-0.9p2 + 0.2025 + p4 = -0.0025 + 0.2025

Reorder the terms:
0.2025 + -0.9p2 + p4 = -0.0025 + 0.2025

Combine like terms: -0.0025 + 0.2025 = 0.2
0.2025 + -0.9p2 + p4 = 0.2

Factor a perfect square on the left side:
(p2 + -0.45)(p2 + -0.45) = 0.2
