15 + 3p + 2p2 = 0

Solving for variable 'p'.

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

Divide each side by '2'.
7.5 + 1.5p + p2 = 0

Move the constant term to the right:

Add '-7.5' to each side of the equation.
7.5 + 1.5p + -7.5 + p2 = 0 + -7.5

Reorder the terms:
7.5 + -7.5 + 1.5p + p2 = 0 + -7.5

Combine like terms: 7.5 + -7.5 = 0.0
0.0 + 1.5p + p2 = 0 + -7.5
1.5p + p2 = 0 + -7.5

Combine like terms: 0 + -7.5 = -7.5
1.5p + p2 = -7.5

The p term is 1.5p.  Take half its coefficient (0.75).
Square it (0.5625) and add it to both sides.

Add '0.5625' to each side of the equation.
1.5p + 0.5625 + p2 = -7.5 + 0.5625

Reorder the terms:
0.5625 + 1.5p + p2 = -7.5 + 0.5625

Combine like terms: -7.5 + 0.5625 = -6.9375
0.5625 + 1.5p + p2 = -6.9375

Factor a perfect square on the left side:
(p + 0.75)(p + 0.75) = -6.9375

Can't calculate square root of the right side.

The solution to this equation could not be determined.
