Simplifying (-2k + 8) * k = 1 Reorder the terms: (8 + -2k) * k = 1 Reorder the terms for easier multiplication: k(8 + -2k) = 1 (8 * k + -2k * k) = 1 (8k + -2k2) = 1 Solving 8k + -2k2 = 1 Solving for variable 'k'. Reorder the terms: -1 + 8k + -2k2 = 1 + -1 Combine like terms: 1 + -1 = 0 -1 + 8k + -2k2 = 0 Begin completing the square. Divide all terms by -2 the coefficient of the squared term: Divide each side by '-2'. 0.5 + -4k + k2 = 0 Move the constant term to the right: Add '-0.5' to each side of the equation. 0.5 + -4k + -0.5 + k2 = 0 + -0.5 Reorder the terms: 0.5 + -0.5 + -4k + k2 = 0 + -0.5 Combine like terms: 0.5 + -0.5 = 0.0 0.0 + -4k + k2 = 0 + -0.5 -4k + k2 = 0 + -0.5 Combine like terms: 0 + -0.5 = -0.5 -4k + k2 = -0.5 The k term is -4k. Take half its coefficient (-2). Square it (4) and add it to both sides. Add '4' to each side of the equation. -4k + 4 + k2 = -0.5 + 4 Reorder the terms: 4 + -4k + k2 = -0.5 + 4 Combine like terms: -0.5 + 4 = 3.5 4 + -4k + k2 = 3.5 Factor a perfect square on the left side: (k + -2)(k + -2) = 3.5 Calculate the square root of the right side: 1.870828693 Break this problem into two subproblems by setting (k + -2) equal to 1.870828693 and -1.870828693.Subproblem 1
k + -2 = 1.870828693 Simplifying k + -2 = 1.870828693 Reorder the terms: -2 + k = 1.870828693 Solving -2 + k = 1.870828693 Solving for variable 'k'. Move all terms containing k to the left, all other terms to the right. Add '2' to each side of the equation. -2 + 2 + k = 1.870828693 + 2 Combine like terms: -2 + 2 = 0 0 + k = 1.870828693 + 2 k = 1.870828693 + 2 Combine like terms: 1.870828693 + 2 = 3.870828693 k = 3.870828693 Simplifying k = 3.870828693Subproblem 2
k + -2 = -1.870828693 Simplifying k + -2 = -1.870828693 Reorder the terms: -2 + k = -1.870828693 Solving -2 + k = -1.870828693 Solving for variable 'k'. Move all terms containing k to the left, all other terms to the right. Add '2' to each side of the equation. -2 + 2 + k = -1.870828693 + 2 Combine like terms: -2 + 2 = 0 0 + k = -1.870828693 + 2 k = -1.870828693 + 2 Combine like terms: -1.870828693 + 2 = 0.129171307 k = 0.129171307 Simplifying k = 0.129171307Solution
