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

Divide each side by '4'.
1.25 + 0.5p + p2 = 0

Move the constant term to the right:

Add '-1.25' to each side of the equation.
1.25 + 0.5p + -1.25 + p2 = 0 + -1.25

Reorder the terms:
1.25 + -1.25 + 0.5p + p2 = 0 + -1.25

Combine like terms: 1.25 + -1.25 = 0.00
0.00 + 0.5p + p2 = 0 + -1.25
0.5p + p2 = 0 + -1.25

Combine like terms: 0 + -1.25 = -1.25
0.5p + p2 = -1.25

The p term is 0.5p.  Take half its coefficient (0.25).
Square it (0.0625) and add it to both sides.

Add '0.0625' to each side of the equation.
0.5p + 0.0625 + p2 = -1.25 + 0.0625

Reorder the terms:
0.0625 + 0.5p + p2 = -1.25 + 0.0625

Combine like terms: -1.25 + 0.0625 = -1.1875
0.0625 + 0.5p + p2 = -1.1875

Factor a perfect square on the left side:
(p + 0.25)(p + 0.25) = -1.1875

Can't calculate square root of the right side.
