Simplifying w2 + -1w + -18 = 0 Reorder the terms: -18 + -1w + w2 = 0 Solving -18 + -1w + w2 = 0 Solving for variable 'w'. Begin completing the square. Move the constant term to the right: Add '18' to each side of the equation. -18 + -1w + 18 + w2 = 0 + 18 Reorder the terms: -18 + 18 + -1w + w2 = 0 + 18 Combine like terms: -18 + 18 = 0 0 + -1w + w2 = 0 + 18 -1w + w2 = 0 + 18 Combine like terms: 0 + 18 = 18 -1w + w2 = 18 The w term is -1w. Take half its coefficient (-0.5). Square it (0.25) and add it to both sides. Add '0.25' to each side of the equation. -1w + 0.25 + w2 = 18 + 0.25 Reorder the terms: 0.25 + -1w + w2 = 18 + 0.25 Combine like terms: 18 + 0.25 = 18.25 0.25 + -1w + w2 = 18.25 Factor a perfect square on the left side: (w + -0.5)(w + -0.5) = 18.25 Calculate the square root of the right side: 4.272001873 Break this problem into two subproblems by setting (w + -0.5) equal to 4.272001873 and -4.272001873.Subproblem 1
w + -0.5 = 4.272001873 Simplifying w + -0.5 = 4.272001873 Reorder the terms: -0.5 + w = 4.272001873 Solving -0.5 + w = 4.272001873 Solving for variable 'w'. Move all terms containing w to the left, all other terms to the right. Add '0.5' to each side of the equation. -0.5 + 0.5 + w = 4.272001873 + 0.5 Combine like terms: -0.5 + 0.5 = 0.0 0.0 + w = 4.272001873 + 0.5 w = 4.272001873 + 0.5 Combine like terms: 4.272001873 + 0.5 = 4.772001873 w = 4.772001873 Simplifying w = 4.772001873Subproblem 2
w + -0.5 = -4.272001873 Simplifying w + -0.5 = -4.272001873 Reorder the terms: -0.5 + w = -4.272001873 Solving -0.5 + w = -4.272001873 Solving for variable 'w'. Move all terms containing w to the left, all other terms to the right. Add '0.5' to each side of the equation. -0.5 + 0.5 + w = -4.272001873 + 0.5 Combine like terms: -0.5 + 0.5 = 0.0 0.0 + w = -4.272001873 + 0.5 w = -4.272001873 + 0.5 Combine like terms: -4.272001873 + 0.5 = -3.772001873 w = -3.772001873 Simplifying w = -3.772001873Solution
The solution to the problem is based on the solutions from the subproblems. w = {4.772001873, -3.772001873}
