Simplifying w2 + -14w + 39 = 0 Reorder the terms: 39 + -14w + w2 = 0 Solving 39 + -14w + w2 = 0 Solving for variable 'w'. Begin completing the square. Move the constant term to the right: Add '-39' to each side of the equation. 39 + -14w + -39 + w2 = 0 + -39 Reorder the terms: 39 + -39 + -14w + w2 = 0 + -39 Combine like terms: 39 + -39 = 0 0 + -14w + w2 = 0 + -39 -14w + w2 = 0 + -39 Combine like terms: 0 + -39 = -39 -14w + w2 = -39 The w term is -14w. Take half its coefficient (-7). Square it (49) and add it to both sides. Add '49' to each side of the equation. -14w + 49 + w2 = -39 + 49 Reorder the terms: 49 + -14w + w2 = -39 + 49 Combine like terms: -39 + 49 = 10 49 + -14w + w2 = 10 Factor a perfect square on the left side: (w + -7)(w + -7) = 10 Calculate the square root of the right side: 3.16227766 Break this problem into two subproblems by setting (w + -7) equal to 3.16227766 and -3.16227766.Subproblem 1
w + -7 = 3.16227766 Simplifying w + -7 = 3.16227766 Reorder the terms: -7 + w = 3.16227766 Solving -7 + w = 3.16227766 Solving for variable 'w'. Move all terms containing w to the left, all other terms to the right. Add '7' to each side of the equation. -7 + 7 + w = 3.16227766 + 7 Combine like terms: -7 + 7 = 0 0 + w = 3.16227766 + 7 w = 3.16227766 + 7 Combine like terms: 3.16227766 + 7 = 10.16227766 w = 10.16227766 Simplifying w = 10.16227766Subproblem 2
w + -7 = -3.16227766 Simplifying w + -7 = -3.16227766 Reorder the terms: -7 + w = -3.16227766 Solving -7 + w = -3.16227766 Solving for variable 'w'. Move all terms containing w to the left, all other terms to the right. Add '7' to each side of the equation. -7 + 7 + w = -3.16227766 + 7 Combine like terms: -7 + 7 = 0 0 + w = -3.16227766 + 7 w = -3.16227766 + 7 Combine like terms: -3.16227766 + 7 = 3.83772234 w = 3.83772234 Simplifying w = 3.83772234Solution
The solution to the problem is based on the solutions from the subproblems. w = {10.16227766, 3.83772234}
