Divide each side by '2'.
-2.5 + 2p + p2 = 0

Move the constant term to the right:

Add '2.5' to each side of the equation.
-2.5 + 2p + 2.5 + p2 = 0 + 2.5

Reorder the terms:
-2.5 + 2.5 + 2p + p2 = 0 + 2.5

Combine like terms: -2.5 + 2.5 = 0.0
0.0 + 2p + p2 = 0 + 2.5
2p + p2 = 0 + 2.5

Combine like terms: 0 + 2.5 = 2.5
2p + p2 = 2.5

The p term is 2p.  Take half its coefficient (1).
Square it (1) and add it to both sides.

Add '1' to each side of the equation.
2p + 1 + p2 = 2.5 + 1

Reorder the terms:
1 + 2p + p2 = 2.5 + 1

Combine like terms: 2.5 + 1 = 3.5
1 + 2p + p2 = 3.5

Break this problem into two subproblems by setting 
(p + 1) equal to 1.870828693 and -1.870828693.

Subproblem 1
p + 1 = 1.870828693

Simplifying
p + 1 = 1.870828693

Reorder the terms:
1 + p = 1.870828693

Solving
1 + p = 1.870828693

Solving for variable 'p'.

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

Add '-1' to each side of the equation.
1 + -1 + p = 1.870828693 + -1

Combine like terms: 1 + -1 = 0
0 + p = 1.870828693 + -1
p = 1.870828693 + -1

Combine like terms: 1.870828693 + -1 = 0.870828693
p = 0.870828693

Simplifying
p = 0.870828693

Subproblem 2
p + 1 = -1.870828693

Simplifying
p + 1 = -1.870828693

Reorder the terms:
1 + p = -1.870828693

Solving
1 + p = -1.870828693

Solving for variable 'p'.

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

Add '-1' to each side of the equation.
1 + -1 + p = -1.870828693 + -1

Combine like terms: 1 + -1 = 0
0 + p = -1.870828693 + -1
p = -1.870828693 + -1

Combine like terms: -1.870828693 + -1 = -2.870828693
p = -2.870828693

Simplifying
p = -2.870828693

Solution
The solution to the problem is based on the solutions
from the subproblems.
p = {0.870828693, -2.870828693}
Solution
p = {0.870828693, -2.870828693}
