Solving
-5 + 6p + 10p2 = 0

Solving for variable 'p'.

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

Divide each side by '10'.
-0.5 + 0.6p + p2 = 0

Move the constant term to the right:

Add '0.5' to each side of the equation.
-0.5 + 0.6p + 0.5 + p2 = 0 + 0.5

Reorder the terms:
-0.5 + 0.5 + 0.6p + p2 = 0 + 0.5

Combine like terms: -0.5 + 0.5 = 0.0
0.0 + 0.6p + p2 = 0 + 0.5
0.6p + p2 = 0 + 0.5

Combine like terms: 0 + 0.5 = 0.5
0.6p + p2 = 0.5

The p term is 0.6p.  Take half its coefficient (0.3).
Square it (0.09) and add it to both sides.

Add '0.09' to each side of the equation.
0.6p + 0.09 + p2 = 0.5 + 0.09

Reorder the terms:
0.09 + 0.6p + p2 = 0.5 + 0.09

Combine like terms: 0.5 + 0.09 = 0.59
0.09 + 0.6p + p2 = 0.59

Factor a perfect square on the left side:
(p + 0.3)(p + 0.3) = 0.59

Calculate the square root of the right side: 0.768114575

Break this problem into two subproblems by setting 
(p + 0.3) equal to 0.768114575 and -0.768114575.

Subproblem 1

p + 0.3 = 0.768114575 Simplifying p + 0.3 = 0.768114575 Reorder the terms: 0.3 + p = 0.768114575 Solving 0.3 + p = 0.768114575 Solving for variable 'p'. Move all terms containing p to the left, all other terms to the right. Add '-0.3' to each side of the equation. 0.3 + -0.3 + p = 0.768114575 + -0.3 Combine like terms: 0.3 + -0.3 = 0.0 0.0 + p = 0.768114575 + -0.3 p = 0.768114575 + -0.3 Combine like terms: 0.768114575 + -0.3 = 0.468114575 p = 0.468114575 Simplifying p = 0.468114575

Subproblem 2

p + 0.3 = -0.768114575 Simplifying p + 0.3 = -0.768114575 Reorder the terms: 0.3 + p = -0.768114575 Solving 0.3 + p = -0.768114575 Solving for variable 'p'. Move all terms containing p to the left, all other terms to the right. Add '-0.3' to each side of the equation. 0.3 + -0.3 + p = -0.768114575 + -0.3 Combine like terms: 0.3 + -0.3 = 0.0 0.0 + p = -0.768114575 + -0.3 p = -0.768114575 + -0.3 Combine like terms: -0.768114575 + -0.3 = -1.068114575 p = -1.068114575 Simplifying p = -1.068114575
