Simplifying -2(w + 1) * 5w = 3(w + 1) + -2 Reorder the terms: -2(1 + w) * 5w = 3(w + 1) + -2 Reorder the terms for easier multiplication: -2 * 5w(1 + w) = 3(w + 1) + -2 Multiply -2 * 5 -10w(1 + w) = 3(w + 1) + -2 (1 * -10w + w * -10w) = 3(w + 1) + -2 (-10w + -10w2) = 3(w + 1) + -2 Reorder the terms: -10w + -10w2 = 3(1 + w) + -2 -10w + -10w2 = (1 * 3 + w * 3) + -2 -10w + -10w2 = (3 + 3w) + -2 Reorder the terms: -10w + -10w2 = 3 + -2 + 3w Combine like terms: 3 + -2 = 1 -10w + -10w2 = 1 + 3w Solving -10w + -10w2 = 1 + 3w Solving for variable 'w'. Reorder the terms: -1 + -10w + -3w + -10w2 = 1 + 3w + -1 + -3w Combine like terms: -10w + -3w = -13w -1 + -13w + -10w2 = 1 + 3w + -1 + -3w Reorder the terms: -1 + -13w + -10w2 = 1 + -1 + 3w + -3w Combine like terms: 1 + -1 = 0 -1 + -13w + -10w2 = 0 + 3w + -3w -1 + -13w + -10w2 = 3w + -3w Combine like terms: 3w + -3w = 0 -1 + -13w + -10w2 = 0 Factor out the Greatest Common Factor (GCF), '-1'. -1(1 + 13w + 10w2) = 0 Ignore the factor -1.Subproblem 1
Set the factor '(1 + 13w + 10w2)' equal to zero and attempt to solve: Simplifying 1 + 13w + 10w2 = 0 Solving 1 + 13w + 10w2 = 0 Begin completing the square. Divide all terms by 10 the coefficient of the squared term: Divide each side by '10'. 0.1 + 1.3w + w2 = 0.0 Move the constant term to the right: Add '-0.1' to each side of the equation. 0.1 + 1.3w + -0.1 + w2 = 0.0 + -0.1 Reorder the terms: 0.1 + -0.1 + 1.3w + w2 = 0.0 + -0.1 Combine like terms: 0.1 + -0.1 = 0.0 0.0 + 1.3w + w2 = 0.0 + -0.1 1.3w + w2 = 0.0 + -0.1 Combine like terms: 0.0 + -0.1 = -0.1 1.3w + w2 = -0.1 The w term is 1.3w. Take half its coefficient (0.65). Square it (0.4225) and add it to both sides. Add '0.4225' to each side of the equation. 1.3w + 0.4225 + w2 = -0.1 + 0.4225 Reorder the terms: 0.4225 + 1.3w + w2 = -0.1 + 0.4225 Combine like terms: -0.1 + 0.4225 = 0.3225 0.4225 + 1.3w + w2 = 0.3225 Factor a perfect square on the left side: (w + 0.65)(w + 0.65) = 0.3225 Calculate the square root of the right side: 0.567890835 Break this problem into two subproblems by setting (w + 0.65) equal to 0.567890835 and -0.567890835.Subproblem 1
w + 0.65 = 0.567890835 Simplifying w + 0.65 = 0.567890835 Reorder the terms: 0.65 + w = 0.567890835 Solving 0.65 + w = 0.567890835 Solving for variable 'w'. Move all terms containing w to the left, all other terms to the right. Add '-0.65' to each side of the equation. 0.65 + -0.65 + w = 0.567890835 + -0.65 Combine like terms: 0.65 + -0.65 = 0.00 0.00 + w = 0.567890835 + -0.65 w = 0.567890835 + -0.65 Combine like terms: 0.567890835 + -0.65 = -0.082109165 w = -0.082109165 Simplifying w = -0.082109165Subproblem 2
w + 0.65 = -0.567890835 Simplifying w + 0.65 = -0.567890835 Reorder the terms: 0.65 + w = -0.567890835 Solving 0.65 + w = -0.567890835 Solving for variable 'w'. Move all terms containing w to the left, all other terms to the right. Add '-0.65' to each side of the equation. 0.65 + -0.65 + w = -0.567890835 + -0.65 Combine like terms: 0.65 + -0.65 = 0.00 0.00 + w = -0.567890835 + -0.65 w = -0.567890835 + -0.65 Combine like terms: -0.567890835 + -0.65 = -1.217890835 w = -1.217890835 Simplifying w = -1.217890835Solution
