Subproblem 1

Set the factor '(-6 + -7w + w2)' equal to zero and attempt to solve: Simplifying -6 + -7w + w2 = 0 Solving -6 + -7w + w2 = 0 Begin completing the square. Move the constant term to the right: Add '6' to each side of the equation. -6 + -7w + 6 + w2 = 0 + 6 Reorder the terms: -6 + 6 + -7w + w2 = 0 + 6 Combine like terms: -6 + 6 = 0 0 + -7w + w2 = 0 + 6 -7w + w2 = 0 + 6 Combine like terms: 0 + 6 = 6 -7w + w2 = 6 The w term is -7w. Take half its coefficient (-3.5). Square it (12.25) and add it to both sides. Add '12.25' to each side of the equation. -7w + 12.25 + w2 = 6 + 12.25 Reorder the terms: 12.25 + -7w + w2 = 6 + 12.25 Combine like terms: 6 + 12.25 = 18.25 12.25 + -7w + w2 = 18.25 Factor a perfect square on the left side: (w + -3.5)(w + -3.5) = 18.25 Calculate the square root of the right side: 4.272001873 Break this problem into two subproblems by setting (w + -3.5) equal to 4.272001873 and -4.272001873.

Subproblem 1

w + -3.5 = 4.272001873 Simplifying w + -3.5 = 4.272001873 Reorder the terms: -3.5 + w = 4.272001873 Solving -3.5 + w = 4.272001873 Solving for variable 'w'. Move all terms containing w to the left, all other terms to the right. Add '3.5' to each side of the equation. -3.5 + 3.5 + w = 4.272001873 + 3.5 Combine like terms: -3.5 + 3.5 = 0.0 0.0 + w = 4.272001873 + 3.5 w = 4.272001873 + 3.5 Combine like terms: 4.272001873 + 3.5 = 7.772001873 w = 7.772001873 Simplifying w = 7.772001873

Subproblem 2

w + -3.5 = -4.272001873 Simplifying w + -3.5 = -4.272001873 Reorder the terms: -3.5 + w = -4.272001873 Solving -3.5 + w = -4.272001873 Solving for variable 'w'. Move all terms containing w to the left, all other terms to the right. Add '3.5' to each side of the equation. -3.5 + 3.5 + w = -4.272001873 + 3.5 Combine like terms: -3.5 + 3.5 = 0.0 0.0 + w = -4.272001873 + 3.5 w = -4.272001873 + 3.5 Combine like terms: -4.272001873 + 3.5 = -0.772001873 w = -0.772001873 Simplifying w = -0.772001873
