Solving for variable 'p'.

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

Divide each side by '4'.
-0.75 + -1.25p + p2 = 0

Move the constant term to the right:

Add '0.75' to each side of the equation.
-0.75 + -1.25p + 0.75 + p2 = 0 + 0.75

Reorder the terms:
-0.75 + 0.75 + -1.25p + p2 = 0 + 0.75

Combine like terms: -0.75 + 0.75 = 0.00
0.00 + -1.25p + p2 = 0 + 0.75
-1.25p + p2 = 0 + 0.75

Combine like terms: 0 + 0.75 = 0.75
-1.25p + p2 = 0.75

The p term is -1.25p.  Take half its coefficient (-0.625).
Square it (0.390625) and add it to both sides.

Add '0.390625' to each side of the equation.
-1.25p + 0.390625 + p2 = 0.75 + 0.390625

Reorder the terms:
0.390625 + -1.25p + p2 = 0.75 + 0.390625

Combine like terms: 0.75 + 0.390625 = 1.140625
0.390625 + -1.25p + p2 = 1.140625
