Simplifying 10k2 + 5k + -4 = 0 Reorder the terms: -4 + 5k + 10k2 = 0 Solving -4 + 5k + 10k2 = 0 Solving for variable 'k'. Begin completing the square. Divide all terms by 10 the coefficient of the squared term: Divide each side by '10'. -0.4 + 0.5k + k2 = 0 Move the constant term to the right: Add '0.4' to each side of the equation. -0.4 + 0.5k + 0.4 + k2 = 0 + 0.4 Reorder the terms: -0.4 + 0.4 + 0.5k + k2 = 0 + 0.4 Combine like terms: -0.4 + 0.4 = 0.0 0.0 + 0.5k + k2 = 0 + 0.4 0.5k + k2 = 0 + 0.4 Combine like terms: 0 + 0.4 = 0.4 0.5k + k2 = 0.4 The k term is 0.5k. Take half its coefficient (0.25). Square it (0.0625) and add it to both sides. Add '0.0625' to each side of the equation. 0.5k + 0.0625 + k2 = 0.4 + 0.0625 Reorder the terms: 0.0625 + 0.5k + k2 = 0.4 + 0.0625 Combine like terms: 0.4 + 0.0625 = 0.4625 0.0625 + 0.5k + k2 = 0.4625 Factor a perfect square on the left side: (k + 0.25)(k + 0.25) = 0.4625 Calculate the square root of the right side: 0.680073525 Break this problem into two subproblems by setting (k + 0.25) equal to 0.680073525 and -0.680073525.Subproblem 1
k + 0.25 = 0.680073525 Simplifying k + 0.25 = 0.680073525 Reorder the terms: 0.25 + k = 0.680073525 Solving 0.25 + k = 0.680073525 Solving for variable 'k'. Move all terms containing k to the left, all other terms to the right. Add '-0.25' to each side of the equation. 0.25 + -0.25 + k = 0.680073525 + -0.25 Combine like terms: 0.25 + -0.25 = 0.00 0.00 + k = 0.680073525 + -0.25 k = 0.680073525 + -0.25 Combine like terms: 0.680073525 + -0.25 = 0.430073525 k = 0.430073525 Simplifying k = 0.430073525Subproblem 2
k + 0.25 = -0.680073525 Simplifying k + 0.25 = -0.680073525 Reorder the terms: 0.25 + k = -0.680073525 Solving 0.25 + k = -0.680073525 Solving for variable 'k'. Move all terms containing k to the left, all other terms to the right. Add '-0.25' to each side of the equation. 0.25 + -0.25 + k = -0.680073525 + -0.25 Combine like terms: 0.25 + -0.25 = 0.00 0.00 + k = -0.680073525 + -0.25 k = -0.680073525 + -0.25 Combine like terms: -0.680073525 + -0.25 = -0.930073525 k = -0.930073525 Simplifying k = -0.930073525Solution
