Simplifying k2 + -1k = 3 Reorder the terms: -1k + k2 = 3 Solving -1k + k2 = 3 Solving for variable 'k'. Reorder the terms: -3 + -1k + k2 = 3 + -3 Combine like terms: 3 + -3 = 0 -3 + -1k + k2 = 0 Begin completing the square. Move the constant term to the right: Add '3' to each side of the equation. -3 + -1k + 3 + k2 = 0 + 3 Reorder the terms: -3 + 3 + -1k + k2 = 0 + 3 Combine like terms: -3 + 3 = 0 0 + -1k + k2 = 0 + 3 -1k + k2 = 0 + 3 Combine like terms: 0 + 3 = 3 -1k + k2 = 3 The k term is -1k. 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. -1k + 0.25 + k2 = 3 + 0.25 Reorder the terms: 0.25 + -1k + k2 = 3 + 0.25 Combine like terms: 3 + 0.25 = 3.25 0.25 + -1k + k2 = 3.25 Factor a perfect square on the left side: (k + -0.5)(k + -0.5) = 3.25 Calculate the square root of the right side: 1.802775638 Break this problem into two subproblems by setting (k + -0.5) equal to 1.802775638 and -1.802775638.Subproblem 1
k + -0.5 = 1.802775638 Simplifying k + -0.5 = 1.802775638 Reorder the terms: -0.5 + k = 1.802775638 Solving -0.5 + k = 1.802775638 Solving for variable 'k'. Move all terms containing k to the left, all other terms to the right. Add '0.5' to each side of the equation. -0.5 + 0.5 + k = 1.802775638 + 0.5 Combine like terms: -0.5 + 0.5 = 0.0 0.0 + k = 1.802775638 + 0.5 k = 1.802775638 + 0.5 Combine like terms: 1.802775638 + 0.5 = 2.302775638 k = 2.302775638 Simplifying k = 2.302775638Subproblem 2
k + -0.5 = -1.802775638 Simplifying k + -0.5 = -1.802775638 Reorder the terms: -0.5 + k = -1.802775638 Solving -0.5 + k = -1.802775638 Solving for variable 'k'. Move all terms containing k to the left, all other terms to the right. Add '0.5' to each side of the equation. -0.5 + 0.5 + k = -1.802775638 + 0.5 Combine like terms: -0.5 + 0.5 = 0.0 0.0 + k = -1.802775638 + 0.5 k = -1.802775638 + 0.5 Combine like terms: -1.802775638 + 0.5 = -1.302775638 k = -1.302775638 Simplifying k = -1.302775638Solution
The solution to the problem is based on the solutions from the subproblems. k = {2.302775638, -1.302775638}
