Solving for variable 'w'.

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

Divide each side by '55'.
-0.05454545455 + 0.4w + w2 = 0

Move the constant term to the right:

Add '0.05454545455' to each side of the equation.
-0.05454545455 + 0.4w + 0.05454545455 + w2 = 0 + 0.05454545455

Reorder the terms:
-0.05454545455 + 0.05454545455 + 0.4w + w2 = 0 + 0.05454545455

Combine like terms: -0.05454545455 + 0.05454545455 = 0.00000000000
0.00000000000 + 0.4w + w2 = 0 + 0.05454545455
0.4w + w2 = 0 + 0.05454545455

Combine like terms: 0 + 0.05454545455 = 0.05454545455
0.4w + w2 = 0.05454545455

The w term is 0.4w.  Take half its coefficient (0.2).
Square it (0.04) and add it to both sides.

Add '0.04' to each side of the equation.
0.4w + 0.04 + w2 = 0.05454545455 + 0.04

Reorder the terms:
0.04 + 0.4w + w2 = 0.05454545455 + 0.04

Combine like terms: 0.05454545455 + 0.04 = 0.09454545455
0.04 + 0.4w + w2 = 0.09454545455

Break this problem into two subproblems by setting 
(w + 0.2) equal to 0.307482446 and -0.307482446.

Subproblem 1

w + 0.2 = 0.307482446 Simplifying w + 0.2 = 0.307482446 Reorder the terms: 0.2 + w = 0.307482446 Solving 0.2 + w = 0.307482446 Solving for variable 'w'. Move all terms containing w to the left, all other terms to the right. Add '-0.2' to each side of the equation. 0.2 + -0.2 + w = 0.307482446 + -0.2 Combine like terms: 0.2 + -0.2 = 0.0 0.0 + w = 0.307482446 + -0.2 w = 0.307482446 + -0.2 Combine like terms: 0.307482446 + -0.2 = 0.107482446 w = 0.107482446 Simplifying w = 0.107482446

Subproblem 2

w + 0.2 = -0.307482446 Simplifying w + 0.2 = -0.307482446 Reorder the terms: 0.2 + w = -0.307482446 Solving 0.2 + w = -0.307482446 Solving for variable 'w'. Move all terms containing w to the left, all other terms to the right. Add '-0.2' to each side of the equation. 0.2 + -0.2 + w = -0.307482446 + -0.2 Combine like terms: 0.2 + -0.2 = 0.0 0.0 + w = -0.307482446 + -0.2 w = -0.307482446 + -0.2 Combine like terms: -0.307482446 + -0.2 = -0.507482446 w = -0.507482446 Simplifying w = -0.507482446

Solution

The solution to the problem is based on the solutions from the subproblems. w = {0.107482446, -0.507482446}
