Solving for variable 'w'.

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

Divide each side by '10'.
-0.3 + -0.5w + w2 = 0

Move the constant term to the right:

Add '0.3' to each side of the equation.
-0.3 + -0.5w + 0.3 + w2 = 0 + 0.3

Reorder the terms:
-0.3 + 0.3 + -0.5w + w2 = 0 + 0.3

Combine like terms: -0.3 + 0.3 = 0.0
0.0 + -0.5w + w2 = 0 + 0.3
-0.5w + w2 = 0 + 0.3

Combine like terms: 0 + 0.3 = 0.3
-0.5w + w2 = 0.3

The w term is -0.5w.  Take half its coefficient (-0.25).
Square it (0.0625) and add it to both sides.

Add '0.0625' to each side of the equation.
-0.5w + 0.0625 + w2 = 0.3 + 0.0625

Reorder the terms:
0.0625 + -0.5w + w2 = 0.3 + 0.0625

Combine like terms: 0.3 + 0.0625 = 0.3625
0.0625 + -0.5w + w2 = 0.3625

Factor a perfect square on the left side:
(w + -0.25)(w + -0.25) = 0.3625

Calculate the square root of the right side: 0.602079729

Break this problem into two subproblems by setting 
(w + -0.25) equal to 0.602079729 and -0.602079729.

Subproblem 1

w + -0.25 = 0.602079729 Simplifying w + -0.25 = 0.602079729 Reorder the terms: -0.25 + w = 0.602079729 Solving -0.25 + w = 0.602079729 Solving for variable 'w'. Move all terms containing w to the left, all other terms to the right. Add '0.25' to each side of the equation. -0.25 + 0.25 + w = 0.602079729 + 0.25 Combine like terms: -0.25 + 0.25 = 0.00 0.00 + w = 0.602079729 + 0.25 w = 0.602079729 + 0.25 Combine like terms: 0.602079729 + 0.25 = 0.852079729 w = 0.852079729 Simplifying w = 0.852079729

Subproblem 2

w + -0.25 = -0.602079729 Simplifying w + -0.25 = -0.602079729 Reorder the terms: -0.25 + w = -0.602079729 Solving -0.25 + w = -0.602079729 Solving for variable 'w'. Move all terms containing w to the left, all other terms to the right. Add '0.25' to each side of the equation. -0.25 + 0.25 + w = -0.602079729 + 0.25 Combine like terms: -0.25 + 0.25 = 0.00 0.00 + w = -0.602079729 + 0.25 w = -0.602079729 + 0.25 Combine like terms: -0.602079729 + 0.25 = -0.352079729 w = -0.352079729 Simplifying w = -0.352079729
