Simplifying (7w2 + -4w + -1) + (3w2 + -6w + 2) = 0 Reorder the terms: (-1 + -4w + 7w2) + (3w2 + -6w + 2) = 0 Remove parenthesis around (-1 + -4w + 7w2) -1 + -4w + 7w2 + (3w2 + -6w + 2) = 0 Reorder the terms: -1 + -4w + 7w2 + (2 + -6w + 3w2) = 0 Remove parenthesis around (2 + -6w + 3w2) -1 + -4w + 7w2 + 2 + -6w + 3w2 = 0 Reorder the terms: -1 + 2 + -4w + -6w + 7w2 + 3w2 = 0 Combine like terms: -1 + 2 = 1 1 + -4w + -6w + 7w2 + 3w2 = 0 Combine like terms: -4w + -6w = -10w 1 + -10w + 7w2 + 3w2 = 0 Combine like terms: 7w2 + 3w2 = 10w2 1 + -10w + 10w2 = 0 Solving 1 + -10w + 10w2 = 0 Solving for variable 'w'. Begin completing the square. Divide all terms by 10 the coefficient of the squared term: Divide each side by '10'. 0.1 + -1w + w2 = 0.0 Move the constant term to the right: Add '-0.1' to each side of the equation. 0.1 + -1w + -0.1 + w2 = 0.0 + -0.1 Reorder the terms: 0.1 + -0.1 + -1w + w2 = 0.0 + -0.1 Combine like terms: 0.1 + -0.1 = 0.0 0.0 + -1w + w2 = 0.0 + -0.1 -1w + w2 = 0.0 + -0.1 Combine like terms: 0.0 + -0.1 = -0.1 -1w + w2 = -0.1 The w term is -1w. Take half its coefficient (-0.5). Square it (0.25) and add it to both sides. Add '0.25' to each side of the equation. -1w + 0.25 + w2 = -0.1 + 0.25 Reorder the terms: 0.25 + -1w + w2 = -0.1 + 0.25 Combine like terms: -0.1 + 0.25 = 0.15 0.25 + -1w + w2 = 0.15 Factor a perfect square on the left side: (w + -0.5)(w + -0.5) = 0.15 Calculate the square root of the right side: 0.387298335 Break this problem into two subproblems by setting (w + -0.5) equal to 0.387298335 and -0.387298335.Subproblem 1
w + -0.5 = 0.387298335 Simplifying w + -0.5 = 0.387298335 Reorder the terms: -0.5 + w = 0.387298335 Solving -0.5 + w = 0.387298335 Solving for variable 'w'. Move all terms containing w to the left, all other terms to the right. Add '0.5' to each side of the equation. -0.5 + 0.5 + w = 0.387298335 + 0.5 Combine like terms: -0.5 + 0.5 = 0.0 0.0 + w = 0.387298335 + 0.5 w = 0.387298335 + 0.5 Combine like terms: 0.387298335 + 0.5 = 0.887298335 w = 0.887298335 Simplifying w = 0.887298335Subproblem 2
w + -0.5 = -0.387298335 Simplifying w + -0.5 = -0.387298335 Reorder the terms: -0.5 + w = -0.387298335 Solving -0.5 + w = -0.387298335 Solving for variable 'w'. Move all terms containing w to the left, all other terms to the right. Add '0.5' to each side of the equation. -0.5 + 0.5 + w = -0.387298335 + 0.5 Combine like terms: -0.5 + 0.5 = 0.0 0.0 + w = -0.387298335 + 0.5 w = -0.387298335 + 0.5 Combine like terms: -0.387298335 + 0.5 = 0.112701665 w = 0.112701665 Simplifying w = 0.112701665Solution
The solution to the problem is based on the solutions from the subproblems. w = {0.887298335, 0.112701665}
