Subproblem 1

Set the factor '(-4 + -4w + w2)' equal to zero and attempt to solve: Simplifying -4 + -4w + w2 = 0 Solving -4 + -4w + w2 = 0 Begin completing the square. Move the constant term to the right: Add '4' to each side of the equation. -4 + -4w + 4 + w2 = 0 + 4 Reorder the terms: -4 + 4 + -4w + w2 = 0 + 4 Combine like terms: -4 + 4 = 0 0 + -4w + w2 = 0 + 4 -4w + w2 = 0 + 4 Combine like terms: 0 + 4 = 4 -4w + w2 = 4 The w term is -4w. Take half its coefficient (-2). Square it (4) and add it to both sides. Add '4' to each side of the equation. -4w + 4 + w2 = 4 + 4 Reorder the terms: 4 + -4w + w2 = 4 + 4 Combine like terms: 4 + 4 = 8 4 + -4w + w2 = 8 Factor a perfect square on the left side: (w + -2)(w + -2) = 8 Calculate the square root of the right side: 2.828427125 Break this problem into two subproblems by setting (w + -2) equal to 2.828427125 and -2.828427125.

Subproblem 1

w + -2 = 2.828427125 Simplifying w + -2 = 2.828427125 Reorder the terms: -2 + w = 2.828427125 Solving -2 + w = 2.828427125 Solving for variable 'w'. Move all terms containing w to the left, all other terms to the right. Add '2' to each side of the equation. -2 + 2 + w = 2.828427125 + 2 Combine like terms: -2 + 2 = 0 0 + w = 2.828427125 + 2 w = 2.828427125 + 2 Combine like terms: 2.828427125 + 2 = 4.828427125 w = 4.828427125 Simplifying w = 4.828427125

Subproblem 2

w + -2 = -2.828427125 Simplifying w + -2 = -2.828427125 Reorder the terms: -2 + w = -2.828427125 Solving -2 + w = -2.828427125 Solving for variable 'w'. Move all terms containing w to the left, all other terms to the right. Add '2' to each side of the equation. -2 + 2 + w = -2.828427125 + 2 Combine like terms: -2 + 2 = 0 0 + w = -2.828427125 + 2 w = -2.828427125 + 2 Combine like terms: -2.828427125 + 2 = -0.828427125 w = -0.828427125 Simplifying w = -0.828427125
