Begin completing the square.

Move the constant term to the right:

Add '6' to each side of the equation.
-6 + 6p + 6 + p2 = 0 + 6

Reorder the terms:
-6 + 6 + 6p + p2 = 0 + 6

Combine like terms: -6 + 6 = 0
0 + 6p + p2 = 0 + 6
6p + p2 = 0 + 6

Combine like terms: 0 + 6 = 6
6p + p2 = 6

The p term is 6p.  Take half its coefficient (3).
Square it (9) and add it to both sides.

Add '9' to each side of the equation.
6p + 9 + p2 = 6 + 9

Reorder the terms:
9 + 6p + p2 = 6 + 9

Combine like terms: 6 + 9 = 15
9 + 6p + p2 = 15

Factor a perfect square on the left side:
(p + 3)(p + 3) = 15

Calculate the square root of the right side: 3.872983346

Break this problem into two subproblems by setting 
(p + 3) equal to 3.872983346 and -3.872983346.

Subproblem 1
p + 3 = 3.872983346

Simplifying
p + 3 = 3.872983346

Reorder the terms:
3 + p = 3.872983346

Solving
3 + p = 3.872983346

Solving for variable 'p'.

Move all terms containing p to the left, all other terms to the right.

Add '-3' to each side of the equation.
3 + -3 + p = 3.872983346 + -3

Combine like terms: 3 + -3 = 0
0 + p = 3.872983346 + -3
p = 3.872983346 + -3

Combine like terms: 3.872983346 + -3 = 0.872983346
p = 0.872983346

Simplifying
p = 0.872983346

Subproblem 2
p + 3 = -3.872983346

Simplifying
p + 3 = -3.872983346

Reorder the terms:
3 + p = -3.872983346

Solving
3 + p = -3.872983346

Solving for variable 'p'.

Move all terms containing p to the left, all other terms to the right.

Add '-3' to each side of the equation.
3 + -3 + p = -3.872983346 + -3

Combine like terms: 3 + -3 = 0
0 + p = -3.872983346 + -3
p = -3.872983346 + -3

Combine like terms: -3.872983346 + -3 = -6.872983346
p = -6.872983346

Simplifying
p = -6.872983346

Solution
The solution to the problem is based on the solutions
from the subproblems.
p = {0.872983346, -6.872983346}
Solution
p = {0.872983346, -6.872983346}
