Solving for variable 'p'.

Begin completing the square.

Move the constant term to the right:

Add '-5' to each side of the equation.
5 + -2p + -5 + p2 = 0 + -5

Reorder the terms:
5 + -5 + -2p + p2 = 0 + -5

Combine like terms: 5 + -5 = 0
0 + -2p + p2 = 0 + -5
-2p + p2 = 0 + -5

Combine like terms: 0 + -5 = -5
-2p + p2 = -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 = -5 + 1

Reorder the terms:
1 + -2p + p2 = -5 + 1

Combine like terms: -5 + 1 = -4
1 + -2p + p2 = -4

Factor a perfect square on the left side:
(p + -1)(p + -1) = -4

Can't calculate square root of the right side.
