Simplifying -1h2 + 6h + -7 = 0 Reorder the terms: -7 + 6h + -1h2 = 0 Solving -7 + 6h + -1h2 = 0 Solving for variable 'h'. Begin completing the square. Divide all terms by -1 the coefficient of the squared term: Divide each side by '-1'. 7 + -6h + h2 = 0 Move the constant term to the right: Add '-7' to each side of the equation. 7 + -6h + -7 + h2 = 0 + -7 Reorder the terms: 7 + -7 + -6h + h2 = 0 + -7 Combine like terms: 7 + -7 = 0 0 + -6h + h2 = 0 + -7 -6h + h2 = 0 + -7 Combine like terms: 0 + -7 = -7 -6h + h2 = -7 The h term is -6h. Take half its coefficient (-3). Square it (9) and add it to both sides. Add '9' to each side of the equation. -6h + 9 + h2 = -7 + 9 Reorder the terms: 9 + -6h + h2 = -7 + 9 Combine like terms: -7 + 9 = 2 9 + -6h + h2 = 2 Factor a perfect square on the left side: (h + -3)(h + -3) = 2 Calculate the square root of the right side: 1.414213562 Break this problem into two subproblems by setting (h + -3) equal to 1.414213562 and -1.414213562.Subproblem 1
h + -3 = 1.414213562 Simplifying h + -3 = 1.414213562 Reorder the terms: -3 + h = 1.414213562 Solving -3 + h = 1.414213562 Solving for variable 'h'. Move all terms containing h to the left, all other terms to the right. Add '3' to each side of the equation. -3 + 3 + h = 1.414213562 + 3 Combine like terms: -3 + 3 = 0 0 + h = 1.414213562 + 3 h = 1.414213562 + 3 Combine like terms: 1.414213562 + 3 = 4.414213562 h = 4.414213562 Simplifying h = 4.414213562Subproblem 2
h + -3 = -1.414213562 Simplifying h + -3 = -1.414213562 Reorder the terms: -3 + h = -1.414213562 Solving -3 + h = -1.414213562 Solving for variable 'h'. Move all terms containing h to the left, all other terms to the right. Add '3' to each side of the equation. -3 + 3 + h = -1.414213562 + 3 Combine like terms: -3 + 3 = 0 0 + h = -1.414213562 + 3 h = -1.414213562 + 3 Combine like terms: -1.414213562 + 3 = 1.585786438 h = 1.585786438 Simplifying h = 1.585786438Solution
The solution to the problem is based on the solutions from the subproblems. h = {4.414213562, 1.585786438}
