Simplifying w2 + -6w + -20 = 0 Reorder the terms: -20 + -6w + w2 = 0 Solving -20 + -6w + w2 = 0 Solving for variable 'w'. Begin completing the square. Move the constant term to the right: Add '20' to each side of the equation. -20 + -6w + 20 + w2 = 0 + 20 Reorder the terms: -20 + 20 + -6w + w2 = 0 + 20 Combine like terms: -20 + 20 = 0 0 + -6w + w2 = 0 + 20 -6w + w2 = 0 + 20 Combine like terms: 0 + 20 = 20 -6w + w2 = 20 The w term is -6w. Take half its coefficient (-3). Square it (9) and add it to both sides. Add '9' to each side of the equation. -6w + 9 + w2 = 20 + 9 Reorder the terms: 9 + -6w + w2 = 20 + 9 Combine like terms: 20 + 9 = 29 9 + -6w + w2 = 29 Factor a perfect square on the left side: (w + -3)(w + -3) = 29 Calculate the square root of the right side: 5.385164807 Break this problem into two subproblems by setting (w + -3) equal to 5.385164807 and -5.385164807.Subproblem 1
w + -3 = 5.385164807 Simplifying w + -3 = 5.385164807 Reorder the terms: -3 + w = 5.385164807 Solving -3 + w = 5.385164807 Solving for variable 'w'. Move all terms containing w to the left, all other terms to the right. Add '3' to each side of the equation. -3 + 3 + w = 5.385164807 + 3 Combine like terms: -3 + 3 = 0 0 + w = 5.385164807 + 3 w = 5.385164807 + 3 Combine like terms: 5.385164807 + 3 = 8.385164807 w = 8.385164807 Simplifying w = 8.385164807Subproblem 2
w + -3 = -5.385164807 Simplifying w + -3 = -5.385164807 Reorder the terms: -3 + w = -5.385164807 Solving -3 + w = -5.385164807 Solving for variable 'w'. Move all terms containing w to the left, all other terms to the right. Add '3' to each side of the equation. -3 + 3 + w = -5.385164807 + 3 Combine like terms: -3 + 3 = 0 0 + w = -5.385164807 + 3 w = -5.385164807 + 3 Combine like terms: -5.385164807 + 3 = -2.385164807 w = -2.385164807 Simplifying w = -2.385164807Solution
The solution to the problem is based on the solutions from the subproblems. w = {8.385164807, -2.385164807}
