Solving for variable 'w'.

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

Divide each side by '2'.
-1.5 + w + w2 = 0

Move the constant term to the right:

Add '1.5' to each side of the equation.
-1.5 + w + 1.5 + w2 = 0 + 1.5

Reorder the terms:
-1.5 + 1.5 + w + w2 = 0 + 1.5

Combine like terms: -1.5 + 1.5 = 0.0
0.0 + w + w2 = 0 + 1.5
w + w2 = 0 + 1.5

Combine like terms: 0 + 1.5 = 1.5
w + w2 = 1.5

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

Add '0.25' to each side of the equation.
 + 0.25 + w2 = 1.5 + 0.25

Combine like terms:  + 0.25 = 1.25
1.25 + w2 = 1.5 + 0.25

Combine like terms: 1.5 + 0.25 = 1.75
1.25 + w2 = 1.75

Factor a perfect square on the left side:
(w + 0.5)(w + 0.5) = 1.75

Calculate the square root of the right side: 1.322875656

Break this problem into two subproblems by setting 
(w + 0.5) equal to 1.322875656 and -1.322875656.

Subproblem 1

w + 0.5 = 1.322875656 Simplifying w + 0.5 = 1.322875656 Reorder the terms: 0.5 + w = 1.322875656 Solving 0.5 + w = 1.322875656 Solving for variable 'w'. Move all terms containing w to the left, all other terms to the right. Add '-0.5' to each side of the equation. 0.5 + -0.5 + w = 1.322875656 + -0.5 Combine like terms: 0.5 + -0.5 = 0.0 0.0 + w = 1.322875656 + -0.5 w = 1.322875656 + -0.5 Combine like terms: 1.322875656 + -0.5 = 0.822875656 w = 0.822875656 Simplifying w = 0.822875656

Subproblem 2

w + 0.5 = -1.322875656 Simplifying w + 0.5 = -1.322875656 Reorder the terms: 0.5 + w = -1.322875656 Solving 0.5 + w = -1.322875656 Solving for variable 'w'. Move all terms containing w to the left, all other terms to the right. Add '-0.5' to each side of the equation. 0.5 + -0.5 + w = -1.322875656 + -0.5 Combine like terms: 0.5 + -0.5 = 0.0 0.0 + w = -1.322875656 + -0.5 w = -1.322875656 + -0.5 Combine like terms: -1.322875656 + -0.5 = -1.822875656 w = -1.822875656 Simplifying w = -1.822875656
