Simplifying k2 + -16k + 52 = 0 Reorder the terms: 52 + -16k + k2 = 0 Solving 52 + -16k + k2 = 0 Solving for variable 'k'. Begin completing the square. Move the constant term to the right: Add '-52' to each side of the equation. 52 + -16k + -52 + k2 = 0 + -52 Reorder the terms: 52 + -52 + -16k + k2 = 0 + -52 Combine like terms: 52 + -52 = 0 0 + -16k + k2 = 0 + -52 -16k + k2 = 0 + -52 Combine like terms: 0 + -52 = -52 -16k + k2 = -52 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 = -52 + 64 Reorder the terms: 64 + -16k + k2 = -52 + 64 Combine like terms: -52 + 64 = 12 64 + -16k + k2 = 12 Factor a perfect square on the left side: (k + -8)(k + -8) = 12 Calculate the square root of the right side: 3.464101615 Break this problem into two subproblems by setting (k + -8) equal to 3.464101615 and -3.464101615.Subproblem 1
k + -8 = 3.464101615 Simplifying k + -8 = 3.464101615 Reorder the terms: -8 + k = 3.464101615 Solving -8 + k = 3.464101615 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 = 3.464101615 + 8 Combine like terms: -8 + 8 = 0 0 + k = 3.464101615 + 8 k = 3.464101615 + 8 Combine like terms: 3.464101615 + 8 = 11.464101615 k = 11.464101615 Simplifying k = 11.464101615Subproblem 2
k + -8 = -3.464101615 Simplifying k + -8 = -3.464101615 Reorder the terms: -8 + k = -3.464101615 Solving -8 + k = -3.464101615 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 = -3.464101615 + 8 Combine like terms: -8 + 8 = 0 0 + k = -3.464101615 + 8 k = -3.464101615 + 8 Combine like terms: -3.464101615 + 8 = 4.535898385 k = 4.535898385 Simplifying k = 4.535898385Solution
