Simplifying -7h2 + 7h + 5 = 0 Reorder the terms: 5 + 7h + -7h2 = 0 Solving 5 + 7h + -7h2 = 0 Solving for variable 'h'. Begin completing the square. Divide all terms by -7 the coefficient of the squared term: Divide each side by '-7'. -0.7142857143 + -1h + h2 = 0 Move the constant term to the right: Add '0.7142857143' to each side of the equation. -0.7142857143 + -1h + 0.7142857143 + h2 = 0 + 0.7142857143 Reorder the terms: -0.7142857143 + 0.7142857143 + -1h + h2 = 0 + 0.7142857143 Combine like terms: -0.7142857143 + 0.7142857143 = 0.0000000000 0.0000000000 + -1h + h2 = 0 + 0.7142857143 -1h + h2 = 0 + 0.7142857143 Combine like terms: 0 + 0.7142857143 = 0.7142857143 -1h + h2 = 0.7142857143 The h term is -1h. Take half its coefficient (-0.5). Square it (0.25) and add it to both sides. Add '0.25' to each side of the equation. -1h + 0.25 + h2 = 0.7142857143 + 0.25 Reorder the terms: 0.25 + -1h + h2 = 0.7142857143 + 0.25 Combine like terms: 0.7142857143 + 0.25 = 0.9642857143 0.25 + -1h + h2 = 0.9642857143 Factor a perfect square on the left side: (h + -0.5)(h + -0.5) = 0.9642857143 Calculate the square root of the right side: 0.981980506 Break this problem into two subproblems by setting (h + -0.5) equal to 0.981980506 and -0.981980506.Subproblem 1
h + -0.5 = 0.981980506 Simplifying h + -0.5 = 0.981980506 Reorder the terms: -0.5 + h = 0.981980506 Solving -0.5 + h = 0.981980506 Solving for variable 'h'. Move all terms containing h to the left, all other terms to the right. Add '0.5' to each side of the equation. -0.5 + 0.5 + h = 0.981980506 + 0.5 Combine like terms: -0.5 + 0.5 = 0.0 0.0 + h = 0.981980506 + 0.5 h = 0.981980506 + 0.5 Combine like terms: 0.981980506 + 0.5 = 1.481980506 h = 1.481980506 Simplifying h = 1.481980506Subproblem 2
h + -0.5 = -0.981980506 Simplifying h + -0.5 = -0.981980506 Reorder the terms: -0.5 + h = -0.981980506 Solving -0.5 + h = -0.981980506 Solving for variable 'h'. Move all terms containing h to the left, all other terms to the right. Add '0.5' to each side of the equation. -0.5 + 0.5 + h = -0.981980506 + 0.5 Combine like terms: -0.5 + 0.5 = 0.0 0.0 + h = -0.981980506 + 0.5 h = -0.981980506 + 0.5 Combine like terms: -0.981980506 + 0.5 = -0.481980506 h = -0.481980506 Simplifying h = -0.481980506Solution
The solution to the problem is based on the solutions from the subproblems. h = {1.481980506, -0.481980506}
