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

Divide each side by '2.5'.
1.44 + -2.4w + w2 = 0

Move the constant term to the right:

Add '-1.44' to each side of the equation.
1.44 + -2.4w + -1.44 + w2 = 0 + -1.44

Reorder the terms:
1.44 + -1.44 + -2.4w + w2 = 0 + -1.44

Combine like terms: 1.44 + -1.44 = 0.00
0.00 + -2.4w + w2 = 0 + -1.44
-2.4w + w2 = 0 + -1.44

Combine like terms: 0 + -1.44 = -1.44
-2.4w + w2 = -1.44

The w term is -2.4w.  Take half its coefficient (-1.2).
Square it (1.44) and add it to both sides.

Add '1.44' to each side of the equation.
-2.4w + 1.44 + w2 = -1.44 + 1.44

Reorder the terms:
1.44 + -2.4w + w2 = -1.44 + 1.44

Combine like terms: -1.44 + 1.44 = 0.00
1.44 + -2.4w + w2 = 0.00

Factor a perfect square on the left side:
(w + -1.2)(w + -1.2) = 0.00

Calculate the square root of the right side: 0.00

Break this problem into two subproblems by setting 
(w + -1.2) equal to 0.00 and 0.00.

Subproblem 1

w + -1.2 = 0.00 Simplifying w + -1.2 = 0.00 Reorder the terms: -1.2 + w = 0.00 Solving -1.2 + w = 0.00 Solving for variable 'w'. Move all terms containing w to the left, all other terms to the right. Add '1.2' to each side of the equation. -1.2 + 1.2 + w = 0.00 + 1.2 Combine like terms: -1.2 + 1.2 = 0.0 0.0 + w = 0.00 + 1.2 w = 0.00 + 1.2 Combine like terms: 0.00 + 1.2 = 1.2 w = 1.2 Simplifying w = 1.2

Subproblem 2

w + -1.2 = 0.00 Simplifying w + -1.2 = 0.00 Reorder the terms: -1.2 + w = 0.00 Solving -1.2 + w = 0.00 Solving for variable 'w'. Move all terms containing w to the left, all other terms to the right. Add '1.2' to each side of the equation. -1.2 + 1.2 + w = 0.00 + 1.2 Combine like terms: -1.2 + 1.2 = 0.0 0.0 + w = 0.00 + 1.2 w = 0.00 + 1.2 Combine like terms: 0.00 + 1.2 = 1.2 w = 1.2 Simplifying w = 1.2

Solution

The solution to the problem is based on the solutions from the subproblems. w = {1.2, 1.2}
