Simplifying w2 + 12w + -25 = 0 Reorder the terms: -25 + 12w + w2 = 0 Solving -25 + 12w + w2 = 0 Solving for variable 'w'. Begin completing the square. Move the constant term to the right: Add '25' to each side of the equation. -25 + 12w + 25 + w2 = 0 + 25 Reorder the terms: -25 + 25 + 12w + w2 = 0 + 25 Combine like terms: -25 + 25 = 0 0 + 12w + w2 = 0 + 25 12w + w2 = 0 + 25 Combine like terms: 0 + 25 = 25 12w + w2 = 25 The w term is 12w. Take half its coefficient (6). Square it (36) and add it to both sides. Add '36' to each side of the equation. 12w + 36 + w2 = 25 + 36 Reorder the terms: 36 + 12w + w2 = 25 + 36 Combine like terms: 25 + 36 = 61 36 + 12w + w2 = 61 Factor a perfect square on the left side: (w + 6)(w + 6) = 61 Calculate the square root of the right side: 7.810249676 Break this problem into two subproblems by setting (w + 6) equal to 7.810249676 and -7.810249676.Subproblem 1
w + 6 = 7.810249676 Simplifying w + 6 = 7.810249676 Reorder the terms: 6 + w = 7.810249676 Solving 6 + w = 7.810249676 Solving for variable 'w'. Move all terms containing w to the left, all other terms to the right. Add '-6' to each side of the equation. 6 + -6 + w = 7.810249676 + -6 Combine like terms: 6 + -6 = 0 0 + w = 7.810249676 + -6 w = 7.810249676 + -6 Combine like terms: 7.810249676 + -6 = 1.810249676 w = 1.810249676 Simplifying w = 1.810249676Subproblem 2
w + 6 = -7.810249676 Simplifying w + 6 = -7.810249676 Reorder the terms: 6 + w = -7.810249676 Solving 6 + w = -7.810249676 Solving for variable 'w'. Move all terms containing w to the left, all other terms to the right. Add '-6' to each side of the equation. 6 + -6 + w = -7.810249676 + -6 Combine like terms: 6 + -6 = 0 0 + w = -7.810249676 + -6 w = -7.810249676 + -6 Combine like terms: -7.810249676 + -6 = -13.810249676 w = -13.810249676 Simplifying w = -13.810249676Solution
The solution to the problem is based on the solutions from the subproblems. w = {1.810249676, -13.810249676}
