Simplifying 2w2 + 3w + -33 = 0 Reorder the terms: -33 + 3w + 2w2 = 0 Solving -33 + 3w + 2w2 = 0 Solving for variable 'w'. Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. -16.5 + 1.5w + w2 = 0 Move the constant term to the right: Add '16.5' to each side of the equation. -16.5 + 1.5w + 16.5 + w2 = 0 + 16.5 Reorder the terms: -16.5 + 16.5 + 1.5w + w2 = 0 + 16.5 Combine like terms: -16.5 + 16.5 = 0.0 0.0 + 1.5w + w2 = 0 + 16.5 1.5w + w2 = 0 + 16.5 Combine like terms: 0 + 16.5 = 16.5 1.5w + w2 = 16.5 The w term is 1.5w. Take half its coefficient (0.75). Square it (0.5625) and add it to both sides. Add '0.5625' to each side of the equation. 1.5w + 0.5625 + w2 = 16.5 + 0.5625 Reorder the terms: 0.5625 + 1.5w + w2 = 16.5 + 0.5625 Combine like terms: 16.5 + 0.5625 = 17.0625 0.5625 + 1.5w + w2 = 17.0625 Factor a perfect square on the left side: (w + 0.75)(w + 0.75) = 17.0625 Calculate the square root of the right side: 4.13067791 Break this problem into two subproblems by setting (w + 0.75) equal to 4.13067791 and -4.13067791.Subproblem 1
w + 0.75 = 4.13067791 Simplifying w + 0.75 = 4.13067791 Reorder the terms: 0.75 + w = 4.13067791 Solving 0.75 + w = 4.13067791 Solving for variable 'w'. Move all terms containing w to the left, all other terms to the right. Add '-0.75' to each side of the equation. 0.75 + -0.75 + w = 4.13067791 + -0.75 Combine like terms: 0.75 + -0.75 = 0.00 0.00 + w = 4.13067791 + -0.75 w = 4.13067791 + -0.75 Combine like terms: 4.13067791 + -0.75 = 3.38067791 w = 3.38067791 Simplifying w = 3.38067791Subproblem 2
w + 0.75 = -4.13067791 Simplifying w + 0.75 = -4.13067791 Reorder the terms: 0.75 + w = -4.13067791 Solving 0.75 + w = -4.13067791 Solving for variable 'w'. Move all terms containing w to the left, all other terms to the right. Add '-0.75' to each side of the equation. 0.75 + -0.75 + w = -4.13067791 + -0.75 Combine like terms: 0.75 + -0.75 = 0.00 0.00 + w = -4.13067791 + -0.75 w = -4.13067791 + -0.75 Combine like terms: -4.13067791 + -0.75 = -4.88067791 w = -4.88067791 Simplifying w = -4.88067791Solution
The solution to the problem is based on the solutions from the subproblems. w = {3.38067791, -4.88067791}
