Simplifying k2 + 16k + 36 = 0 Reorder the terms: 36 + 16k + k2 = 0 Solving 36 + 16k + k2 = 0 Solving for variable 'k'. Begin completing the square. Move the constant term to the right: Add '-36' to each side of the equation. 36 + 16k + -36 + k2 = 0 + -36 Reorder the terms: 36 + -36 + 16k + k2 = 0 + -36 Combine like terms: 36 + -36 = 0 0 + 16k + k2 = 0 + -36 16k + k2 = 0 + -36 Combine like terms: 0 + -36 = -36 16k + k2 = -36 The k term is 16k. Take half its coefficient (8). Square it (64) and add it to both sides. Add '64' to each side of the equation. 16k + 64 + k2 = -36 + 64 Reorder the terms: 64 + 16k + k2 = -36 + 64 Combine like terms: -36 + 64 = 28 64 + 16k + k2 = 28 Factor a perfect square on the left side: (k + 8)(k + 8) = 28 Calculate the square root of the right side: 5.291502622 Break this problem into two subproblems by setting (k + 8) equal to 5.291502622 and -5.291502622.Subproblem 1
k + 8 = 5.291502622 Simplifying k + 8 = 5.291502622 Reorder the terms: 8 + k = 5.291502622 Solving 8 + k = 5.291502622 Solving for variable 'k'. Move all terms containing k to the left, all other terms to the right. Add '-8' to each side of the equation. 8 + -8 + k = 5.291502622 + -8 Combine like terms: 8 + -8 = 0 0 + k = 5.291502622 + -8 k = 5.291502622 + -8 Combine like terms: 5.291502622 + -8 = -2.708497378 k = -2.708497378 Simplifying k = -2.708497378Subproblem 2
k + 8 = -5.291502622 Simplifying k + 8 = -5.291502622 Reorder the terms: 8 + k = -5.291502622 Solving 8 + k = -5.291502622 Solving for variable 'k'. Move all terms containing k to the left, all other terms to the right. Add '-8' to each side of the equation. 8 + -8 + k = -5.291502622 + -8 Combine like terms: 8 + -8 = 0 0 + k = -5.291502622 + -8 k = -5.291502622 + -8 Combine like terms: -5.291502622 + -8 = -13.291502622 k = -13.291502622 Simplifying k = -13.291502622Solution
