Simplifying 8 = 5w(w + 4) Reorder the terms: 8 = 5w(4 + w) 8 = (4 * 5w + w * 5w) 8 = (20w + 5w2) Solving 8 = 20w + 5w2 Solving for variable 'w'. Reorder the terms: 8 + -20w + -5w2 = 20w + -20w + 5w2 + -5w2 Combine like terms: 20w + -20w = 0 8 + -20w + -5w2 = 0 + 5w2 + -5w2 8 + -20w + -5w2 = 5w2 + -5w2 Combine like terms: 5w2 + -5w2 = 0 8 + -20w + -5w2 = 0 Begin completing the square. Divide all terms by -5 the coefficient of the squared term: Divide each side by '-5'. -1.6 + 4w + w2 = 0 Move the constant term to the right: Add '1.6' to each side of the equation. -1.6 + 4w + 1.6 + w2 = 0 + 1.6 Reorder the terms: -1.6 + 1.6 + 4w + w2 = 0 + 1.6 Combine like terms: -1.6 + 1.6 = 0.0 0.0 + 4w + w2 = 0 + 1.6 4w + w2 = 0 + 1.6 Combine like terms: 0 + 1.6 = 1.6 4w + w2 = 1.6 The w term is 4w. Take half its coefficient (2). Square it (4) and add it to both sides. Add '4' to each side of the equation. 4w + 4 + w2 = 1.6 + 4 Reorder the terms: 4 + 4w + w2 = 1.6 + 4 Combine like terms: 1.6 + 4 = 5.6 4 + 4w + w2 = 5.6 Factor a perfect square on the left side: (w + 2)(w + 2) = 5.6 Calculate the square root of the right side: 2.366431913 Break this problem into two subproblems by setting (w + 2) equal to 2.366431913 and -2.366431913.Subproblem 1
w + 2 = 2.366431913 Simplifying w + 2 = 2.366431913 Reorder the terms: 2 + w = 2.366431913 Solving 2 + w = 2.366431913 Solving for variable 'w'. Move all terms containing w to the left, all other terms to the right. Add '-2' to each side of the equation. 2 + -2 + w = 2.366431913 + -2 Combine like terms: 2 + -2 = 0 0 + w = 2.366431913 + -2 w = 2.366431913 + -2 Combine like terms: 2.366431913 + -2 = 0.366431913 w = 0.366431913 Simplifying w = 0.366431913Subproblem 2
w + 2 = -2.366431913 Simplifying w + 2 = -2.366431913 Reorder the terms: 2 + w = -2.366431913 Solving 2 + w = -2.366431913 Solving for variable 'w'. Move all terms containing w to the left, all other terms to the right. Add '-2' to each side of the equation. 2 + -2 + w = -2.366431913 + -2 Combine like terms: 2 + -2 = 0 0 + w = -2.366431913 + -2 w = -2.366431913 + -2 Combine like terms: -2.366431913 + -2 = -4.366431913 w = -4.366431913 Simplifying w = -4.366431913Solution
The solution to the problem is based on the solutions from the subproblems. w = {0.366431913, -4.366431913}
