Solving for variable 'w'.

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

Divide each side by '4'.
-1.75 + -6w + w2 = 0

Move the constant term to the right:

Add '1.75' to each side of the equation.
-1.75 + -6w + 1.75 + w2 = 0 + 1.75

Reorder the terms:
-1.75 + 1.75 + -6w + w2 = 0 + 1.75

Combine like terms: -1.75 + 1.75 = 0.00
0.00 + -6w + w2 = 0 + 1.75
-6w + w2 = 0 + 1.75

Combine like terms: 0 + 1.75 = 1.75
-6w + w2 = 1.75

The w term is -6w.  Take half its coefficient (-3).
Square it (9) and add it to both sides.

Add '9' to each side of the equation.
-6w + 9 + w2 = 1.75 + 9

Reorder the terms:
9 + -6w + w2 = 1.75 + 9

Combine like terms: 1.75 + 9 = 10.75
9 + -6w + w2 = 10.75

Factor a perfect square on the left side:
(w + -3)(w + -3) = 10.75

Calculate the square root of the right side: 3.278719262

Break this problem into two subproblems by setting 
(w + -3) equal to 3.278719262 and -3.278719262.

Subproblem 1

w + -3 = 3.278719262 Simplifying w + -3 = 3.278719262 Reorder the terms: -3 + w = 3.278719262 Solving -3 + w = 3.278719262 Solving for variable 'w'. Move all terms containing w to the left, all other terms to the right. Add '3' to each side of the equation. -3 + 3 + w = 3.278719262 + 3 Combine like terms: -3 + 3 = 0 0 + w = 3.278719262 + 3 w = 3.278719262 + 3 Combine like terms: 3.278719262 + 3 = 6.278719262 w = 6.278719262 Simplifying w = 6.278719262

Subproblem 2

w + -3 = -3.278719262 Simplifying w + -3 = -3.278719262 Reorder the terms: -3 + w = -3.278719262 Solving -3 + w = -3.278719262 Solving for variable 'w'. Move all terms containing w to the left, all other terms to the right. Add '3' to each side of the equation. -3 + 3 + w = -3.278719262 + 3 Combine like terms: -3 + 3 = 0 0 + w = -3.278719262 + 3 w = -3.278719262 + 3 Combine like terms: -3.278719262 + 3 = -0.278719262 w = -0.278719262 Simplifying w = -0.278719262

Solution
