Simplifying 5k2 = 60 + -2k Solving 5k2 = 60 + -2k Solving for variable 'k'. Reorder the terms: -60 + 2k + 5k2 = 60 + -2k + -60 + 2k Reorder the terms: -60 + 2k + 5k2 = 60 + -60 + -2k + 2k Combine like terms: 60 + -60 = 0 -60 + 2k + 5k2 = 0 + -2k + 2k -60 + 2k + 5k2 = -2k + 2k Combine like terms: -2k + 2k = 0 -60 + 2k + 5k2 = 0 Begin completing the square. Divide all terms by 5 the coefficient of the squared term: Divide each side by '5'. -12 + 0.4k + k2 = 0 Move the constant term to the right: Add '12' to each side of the equation. -12 + 0.4k + 12 + k2 = 0 + 12 Reorder the terms: -12 + 12 + 0.4k + k2 = 0 + 12 Combine like terms: -12 + 12 = 0 0 + 0.4k + k2 = 0 + 12 0.4k + k2 = 0 + 12 Combine like terms: 0 + 12 = 12 0.4k + k2 = 12 The k term is 0.4k. Take half its coefficient (0.2). Square it (0.04) and add it to both sides. Add '0.04' to each side of the equation. 0.4k + 0.04 + k2 = 12 + 0.04 Reorder the terms: 0.04 + 0.4k + k2 = 12 + 0.04 Combine like terms: 12 + 0.04 = 12.04 0.04 + 0.4k + k2 = 12.04 Factor a perfect square on the left side: (k + 0.2)(k + 0.2) = 12.04 Calculate the square root of the right side: 3.469870315 Break this problem into two subproblems by setting (k + 0.2) equal to 3.469870315 and -3.469870315.Subproblem 1
k + 0.2 = 3.469870315 Simplifying k + 0.2 = 3.469870315 Reorder the terms: 0.2 + k = 3.469870315 Solving 0.2 + k = 3.469870315 Solving for variable 'k'. Move all terms containing k to the left, all other terms to the right. Add '-0.2' to each side of the equation. 0.2 + -0.2 + k = 3.469870315 + -0.2 Combine like terms: 0.2 + -0.2 = 0.0 0.0 + k = 3.469870315 + -0.2 k = 3.469870315 + -0.2 Combine like terms: 3.469870315 + -0.2 = 3.269870315 k = 3.269870315 Simplifying k = 3.269870315Subproblem 2
k + 0.2 = -3.469870315 Simplifying k + 0.2 = -3.469870315 Reorder the terms: 0.2 + k = -3.469870315 Solving 0.2 + k = -3.469870315 Solving for variable 'k'. Move all terms containing k to the left, all other terms to the right. Add '-0.2' to each side of the equation. 0.2 + -0.2 + k = -3.469870315 + -0.2 Combine like terms: 0.2 + -0.2 = 0.0 0.0 + k = -3.469870315 + -0.2 k = -3.469870315 + -0.2 Combine like terms: -3.469870315 + -0.2 = -3.669870315 k = -3.669870315 Simplifying k = -3.669870315Solution
The solution to the problem is based on the solutions from the subproblems. k = {3.269870315, -3.669870315}
