Subproblem 1

Set the factor '(-5 + 2w + w2)' equal to zero and attempt to solve: Simplifying -5 + 2w + w2 = 0 Solving -5 + 2w + w2 = 0 Begin completing the square. Move the constant term to the right: Add '5' to each side of the equation. -5 + 2w + 5 + w2 = 0 + 5 Reorder the terms: -5 + 5 + 2w + w2 = 0 + 5 Combine like terms: -5 + 5 = 0 0 + 2w + w2 = 0 + 5 2w + w2 = 0 + 5 Combine like terms: 0 + 5 = 5 2w + w2 = 5 The w term is 2w. Take half its coefficient (1). Square it (1) and add it to both sides. Add '1' to each side of the equation. 2w + 1 + w2 = 5 + 1 Reorder the terms: 1 + 2w + w2 = 5 + 1 Combine like terms: 5 + 1 = 6 1 + 2w + w2 = 6 Factor a perfect square on the left side: (w + 1)(w + 1) = 6 Calculate the square root of the right side: 2.449489743 Break this problem into two subproblems by setting (w + 1) equal to 2.449489743 and -2.449489743.

Subproblem 1

w + 1 = 2.449489743 Simplifying w + 1 = 2.449489743 Reorder the terms: 1 + w = 2.449489743 Solving 1 + w = 2.449489743 Solving for variable 'w'. Move all terms containing w to the left, all other terms to the right. Add '-1' to each side of the equation. 1 + -1 + w = 2.449489743 + -1 Combine like terms: 1 + -1 = 0 0 + w = 2.449489743 + -1 w = 2.449489743 + -1 Combine like terms: 2.449489743 + -1 = 1.449489743 w = 1.449489743 Simplifying w = 1.449489743

Subproblem 2

w + 1 = -2.449489743 Simplifying w + 1 = -2.449489743 Reorder the terms: 1 + w = -2.449489743 Solving 1 + w = -2.449489743 Solving for variable 'w'. Move all terms containing w to the left, all other terms to the right. Add '-1' to each side of the equation. 1 + -1 + w = -2.449489743 + -1 Combine like terms: 1 + -1 = 0 0 + w = -2.449489743 + -1 w = -2.449489743 + -1 Combine like terms: -2.449489743 + -1 = -3.449489743 w = -3.449489743 Simplifying w = -3.449489743
