Simplifying w2 + -20w + 13 = 0 Reorder the terms: 13 + -20w + w2 = 0 Solving 13 + -20w + w2 = 0 Solving for variable 'w'. Begin completing the square. Move the constant term to the right: Add '-13' to each side of the equation. 13 + -20w + -13 + w2 = 0 + -13 Reorder the terms: 13 + -13 + -20w + w2 = 0 + -13 Combine like terms: 13 + -13 = 0 0 + -20w + w2 = 0 + -13 -20w + w2 = 0 + -13 Combine like terms: 0 + -13 = -13 -20w + w2 = -13 The w term is -20w. Take half its coefficient (-10). Square it (100) and add it to both sides. Add '100' to each side of the equation. -20w + 100 + w2 = -13 + 100 Reorder the terms: 100 + -20w + w2 = -13 + 100 Combine like terms: -13 + 100 = 87 100 + -20w + w2 = 87 Factor a perfect square on the left side: (w + -10)(w + -10) = 87 Calculate the square root of the right side: 9.327379053 Break this problem into two subproblems by setting (w + -10) equal to 9.327379053 and -9.327379053.Subproblem 1
w + -10 = 9.327379053 Simplifying w + -10 = 9.327379053 Reorder the terms: -10 + w = 9.327379053 Solving -10 + w = 9.327379053 Solving for variable 'w'. Move all terms containing w to the left, all other terms to the right. Add '10' to each side of the equation. -10 + 10 + w = 9.327379053 + 10 Combine like terms: -10 + 10 = 0 0 + w = 9.327379053 + 10 w = 9.327379053 + 10 Combine like terms: 9.327379053 + 10 = 19.327379053 w = 19.327379053 Simplifying w = 19.327379053Subproblem 2
w + -10 = -9.327379053 Simplifying w + -10 = -9.327379053 Reorder the terms: -10 + w = -9.327379053 Solving -10 + w = -9.327379053 Solving for variable 'w'. Move all terms containing w to the left, all other terms to the right. Add '10' to each side of the equation. -10 + 10 + w = -9.327379053 + 10 Combine like terms: -10 + 10 = 0 0 + w = -9.327379053 + 10 w = -9.327379053 + 10 Combine like terms: -9.327379053 + 10 = 0.672620947 w = 0.672620947 Simplifying w = 0.672620947Solution
The solution to the problem is based on the solutions from the subproblems. w = {19.327379053, 0.672620947}
