Simplifying k2 + 3k + -17 = 0 Reorder the terms: -17 + 3k + k2 = 0 Solving -17 + 3k + k2 = 0 Solving for variable 'k'. Begin completing the square. Move the constant term to the right: Add '17' to each side of the equation. -17 + 3k + 17 + k2 = 0 + 17 Reorder the terms: -17 + 17 + 3k + k2 = 0 + 17 Combine like terms: -17 + 17 = 0 0 + 3k + k2 = 0 + 17 3k + k2 = 0 + 17 Combine like terms: 0 + 17 = 17 3k + k2 = 17 The k term is 3k. Take half its coefficient (1.5). Square it (2.25) and add it to both sides. Add '2.25' to each side of the equation. 3k + 2.25 + k2 = 17 + 2.25 Reorder the terms: 2.25 + 3k + k2 = 17 + 2.25 Combine like terms: 17 + 2.25 = 19.25 2.25 + 3k + k2 = 19.25 Factor a perfect square on the left side: (k + 1.5)(k + 1.5) = 19.25 Calculate the square root of the right side: 4.387482194 Break this problem into two subproblems by setting (k + 1.5) equal to 4.387482194 and -4.387482194.Subproblem 1
k + 1.5 = 4.387482194 Simplifying k + 1.5 = 4.387482194 Reorder the terms: 1.5 + k = 4.387482194 Solving 1.5 + k = 4.387482194 Solving for variable 'k'. Move all terms containing k to the left, all other terms to the right. Add '-1.5' to each side of the equation. 1.5 + -1.5 + k = 4.387482194 + -1.5 Combine like terms: 1.5 + -1.5 = 0.0 0.0 + k = 4.387482194 + -1.5 k = 4.387482194 + -1.5 Combine like terms: 4.387482194 + -1.5 = 2.887482194 k = 2.887482194 Simplifying k = 2.887482194Subproblem 2
k + 1.5 = -4.387482194 Simplifying k + 1.5 = -4.387482194 Reorder the terms: 1.5 + k = -4.387482194 Solving 1.5 + k = -4.387482194 Solving for variable 'k'. Move all terms containing k to the left, all other terms to the right. Add '-1.5' to each side of the equation. 1.5 + -1.5 + k = -4.387482194 + -1.5 Combine like terms: 1.5 + -1.5 = 0.0 0.0 + k = -4.387482194 + -1.5 k = -4.387482194 + -1.5 Combine like terms: -4.387482194 + -1.5 = -5.887482194 k = -5.887482194 Simplifying k = -5.887482194Solution
The solution to the problem is based on the solutions from the subproblems. k = {2.887482194, -5.887482194}
