Simplifying k2 + 6k + -22 = 0 Reorder the terms: -22 + 6k + k2 = 0 Solving -22 + 6k + k2 = 0 Solving for variable 'k'. Begin completing the square. Move the constant term to the right: Add '22' to each side of the equation. -22 + 6k + 22 + k2 = 0 + 22 Reorder the terms: -22 + 22 + 6k + k2 = 0 + 22 Combine like terms: -22 + 22 = 0 0 + 6k + k2 = 0 + 22 6k + k2 = 0 + 22 Combine like terms: 0 + 22 = 22 6k + k2 = 22 The k term is 6k. Take half its coefficient (3). Square it (9) and add it to both sides. Add '9' to each side of the equation. 6k + 9 + k2 = 22 + 9 Reorder the terms: 9 + 6k + k2 = 22 + 9 Combine like terms: 22 + 9 = 31 9 + 6k + k2 = 31 Factor a perfect square on the left side: (k + 3)(k + 3) = 31 Calculate the square root of the right side: 5.567764363 Break this problem into two subproblems by setting (k + 3) equal to 5.567764363 and -5.567764363.Subproblem 1
k + 3 = 5.567764363 Simplifying k + 3 = 5.567764363 Reorder the terms: 3 + k = 5.567764363 Solving 3 + k = 5.567764363 Solving for variable 'k'. Move all terms containing k to the left, all other terms to the right. Add '-3' to each side of the equation. 3 + -3 + k = 5.567764363 + -3 Combine like terms: 3 + -3 = 0 0 + k = 5.567764363 + -3 k = 5.567764363 + -3 Combine like terms: 5.567764363 + -3 = 2.567764363 k = 2.567764363 Simplifying k = 2.567764363Subproblem 2
k + 3 = -5.567764363 Simplifying k + 3 = -5.567764363 Reorder the terms: 3 + k = -5.567764363 Solving 3 + k = -5.567764363 Solving for variable 'k'.
