Simplifying h2 + 9h + -21 = 0 Reorder the terms: -21 + 9h + h2 = 0 Solving -21 + 9h + h2 = 0 Solving for variable 'h'. Begin completing the square. Move the constant term to the right: Add '21' to each side of the equation. -21 + 9h + 21 + h2 = 0 + 21 Reorder the terms: -21 + 21 + 9h + h2 = 0 + 21 Combine like terms: -21 + 21 = 0 0 + 9h + h2 = 0 + 21 9h + h2 = 0 + 21 Combine like terms: 0 + 21 = 21 9h + h2 = 21 The h term is 9h. Take half its coefficient (4.5). Square it (20.25) and add it to both sides. Add '20.25' to each side of the equation. 9h + 20.25 + h2 = 21 + 20.25 Reorder the terms: 20.25 + 9h + h2 = 21 + 20.25 Combine like terms: 21 + 20.25 = 41.25 20.25 + 9h + h2 = 41.25 Factor a perfect square on the left side: (h + 4.5)(h + 4.5) = 41.25 Calculate the square root of the right side: 6.422616289 Break this problem into two subproblems by setting (h + 4.5) equal to 6.422616289 and -6.422616289.Subproblem 1
h + 4.5 = 6.422616289 Simplifying h + 4.5 = 6.422616289 Reorder the terms: 4.5 + h = 6.422616289 Solving 4.5 + h = 6.422616289 Solving for variable 'h'. Move all terms containing h to the left, all other terms to the right. Add '-4.5' to each side of the equation. 4.5 + -4.5 + h = 6.422616289 + -4.5 Combine like terms: 4.5 + -4.5 = 0.0 0.0 + h = 6.422616289 + -4.5 h = 6.422616289 + -4.5 Combine like terms: 6.422616289 + -4.5 = 1.922616289 h = 1.922616289 Simplifying h = 1.922616289Subproblem 2
h + 4.5 = -6.422616289 Simplifying h + 4.5 = -6.422616289 Reorder the terms: 4.5 + h = -6.422616289 Solving 4.5 + h = -6.422616289 Solving for variable 'h'. Move all terms containing h to the left, all other terms to the right. Add '-4.5' to each side of the equation. 4.5 + -4.5 + h = -6.422616289 + -4.5 Combine like terms: 4.5 + -4.5 = 0.0 0.0 + h = -6.422616289 + -4.5 h = -6.422616289 + -4.5 Combine like terms: -6.422616289 + -4.5 = -10.922616289 h = -10.922616289 Simplifying h = -10.922616289Solution
The solution to the problem is based on the solutions from the subproblems. h = {1.922616289, -10.922616289}
