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 + -3p + p2 = 0

Move the constant term to the right:

Add '-0.75' to each side of the equation.
0.75 + -3p + -0.75 + p2 = 0 + -0.75

Reorder the terms:
0.75 + -0.75 + -3p + p2 = 0 + -0.75

Combine like terms: 0.75 + -0.75 = 0.00
0.00 + -3p + p2 = 0 + -0.75
-3p + p2 = 0 + -0.75

Combine like terms: 0 + -0.75 = -0.75
-3p + p2 = -0.75

The p term is -3p.  Take half its coefficient (-1.5).
Square it (2.25) and add it to both sides.

Add '2.25' to each side of the equation.
-3p + 2.25 + p2 = -0.75 + 2.25

Reorder the terms:
2.25 + -3p + p2 = -0.75 + 2.25

Combine like terms: -0.75 + 2.25 = 1.5
2.25 + -3p + p2 = 1.5

Factor a perfect square on the left side:
(p + -1.5)(p + -1.5) = 1.5

Calculate the square root of the right side: 1.224744871
