Simplifying 80 = (2w + -5) * w Reorder the terms: 80 = (-5 + 2w) * w Reorder the terms for easier multiplication: 80 = w(-5 + 2w) 80 = (-5 * w + 2w * w) 80 = (-5w + 2w2) Solving 80 = -5w + 2w2 Solving for variable 'w'. Reorder the terms: 80 + 5w + -2w2 = -5w + 5w + 2w2 + -2w2 Combine like terms: -5w + 5w = 0 80 + 5w + -2w2 = 0 + 2w2 + -2w2 80 + 5w + -2w2 = 2w2 + -2w2 Combine like terms: 2w2 + -2w2 = 0 80 + 5w + -2w2 = 0 Begin completing the square. Divide all terms by -2 the coefficient of the squared term: Divide each side by '-2'. -40 + -2.5w + w2 = 0 Move the constant term to the right: Add '40' to each side of the equation. -40 + -2.5w + 40 + w2 = 0 + 40 Reorder the terms: -40 + 40 + -2.5w + w2 = 0 + 40 Combine like terms: -40 + 40 = 0 0 + -2.5w + w2 = 0 + 40 -2.5w + w2 = 0 + 40 Combine like terms: 0 + 40 = 40 -2.5w + w2 = 40 The w term is -2.5w. Take half its coefficient (-1.25). Square it (1.5625) and add it to both sides. Add '1.5625' to each side of the equation. -2.5w + 1.5625 + w2 = 40 + 1.5625 Reorder the terms: 1.5625 + -2.5w + w2 = 40 + 1.5625 Combine like terms: 40 + 1.5625 = 41.5625 1.5625 + -2.5w + w2 = 41.5625 Factor a perfect square on the left side: (w + -1.25)(w + -1.25) = 41.5625 Calculate the square root of the right side: 6.446898479 Break this problem into two subproblems by setting (w + -1.25) equal to 6.446898479 and -6.446898479.Subproblem 1
w + -1.25 = 6.446898479 Simplifying w + -1.25 = 6.446898479 Reorder the terms: -1.25 + w = 6.446898479 Solving -1.25 + w = 6.446898479 Solving for variable 'w'. Move all terms containing w to the left, all other terms to the right. Add '1.25' to each side of the equation. -1.25 + 1.25 + w = 6.446898479 + 1.25 Combine like terms: -1.25 + 1.25 = 0.00 0.00 + w = 6.446898479 + 1.25 w = 6.446898479 + 1.25 Combine like terms: 6.446898479 + 1.25 = 7.696898479 w = 7.696898479 Simplifying w = 7.696898479Subproblem 2
w + -1.25 = -6.446898479 Simplifying w + -1.25 = -6.446898479 Reorder the terms: -1.25 + w = -6.446898479 Solving -1.25 + w = -6.446898479 Solving for variable 'w'. Move all terms containing w to the left, all other terms to the right. Add '1.25' to each side of the equation. -1.25 + 1.25 + w = -6.446898479 + 1.25 Combine like terms: -1.25 + 1.25 = 0.00 0.00 + w = -6.446898479 + 1.25 w = -6.446898479 + 1.25 Combine like terms: -6.446898479 + 1.25 = -5.196898479 w = -5.196898479 Simplifying w = -5.196898479Solution
The solution to the problem is based on the solutions from the subproblems. w = {7.696898479, -5.196898479}
