Simplifying 2w2 + 18w + 30 = 0 Reorder the terms: 30 + 18w + 2w2 = 0 Solving 30 + 18w + 2w2 = 0 Solving for variable 'w'. Factor out the Greatest Common Factor (GCF), '2'. 2(15 + 9w + w2) = 0 Ignore the factor 2.Subproblem 1
Set the factor '(15 + 9w + w2)' equal to zero and attempt to solve: Simplifying 15 + 9w + w2 = 0 Solving 15 + 9w + w2 = 0 Begin completing the square. Move the constant term to the right: Add '-15' to each side of the equation. 15 + 9w + -15 + w2 = 0 + -15 Reorder the terms: 15 + -15 + 9w + w2 = 0 + -15 Combine like terms: 15 + -15 = 0 0 + 9w + w2 = 0 + -15 9w + w2 = 0 + -15 Combine like terms: 0 + -15 = -15 9w + w2 = -15 The w term is 9w. Take half its coefficient (4.5). Square it (20.25) and add it to both sides. Add '20.25' to each side of the equation. 9w + 20.25 + w2 = -15 + 20.25 Reorder the terms: 20.25 + 9w + w2 = -15 + 20.25 Combine like terms: -15 + 20.25 = 5.25 20.25 + 9w + w2 = 5.25 Factor a perfect square on the left side: (w + 4.5)(w + 4.5) = 5.25 Calculate the square root of the right side: 2.291287847 Break this problem into two subproblems by setting (w + 4.5) equal to 2.291287847 and -2.291287847.Subproblem 1
w + 4.5 = 2.291287847 Simplifying w + 4.5 = 2.291287847 Reorder the terms: 4.5 + w = 2.291287847 Solving 4.5 + w = 2.291287847 Solving for variable 'w'. Move all terms containing w to the left, all other terms to the right. Add '-4.5' to each side of the equation. 4.5 + -4.5 + w = 2.291287847 + -4.5 Combine like terms: 4.5 + -4.5 = 0.0 0.0 + w = 2.291287847 + -4.5 w = 2.291287847 + -4.5 Combine like terms: 2.291287847 + -4.5 = -2.208712153 w = -2.208712153 Simplifying w = -2.208712153Subproblem 2
w + 4.5 = -2.291287847 Simplifying w + 4.5 = -2.291287847 Reorder the terms: 4.5 + w = -2.291287847 Solving 4.5 + w = -2.291287847 Solving for variable 'w'. Move all terms containing w to the left, all other terms to the right. Add '-4.5' to each side of the equation. 4.5 + -4.5 + w = -2.291287847 + -4.5 Combine like terms: 4.5 + -4.5 = 0.0 0.0 + w = -2.291287847 + -4.5 w = -2.291287847 + -4.5 Combine like terms: -2.291287847 + -4.5 = -6.791287847 w = -6.791287847 Simplifying w = -6.791287847Solution
The solution to the problem is based on the solutions from the subproblems. w = {-2.208712153, -6.791287847}Solution
w = {-2.208712153, -6.791287847}
