Simplifying h2 + 15h + -90 = 0 Reorder the terms: -90 + 15h + h2 = 0 Solving -90 + 15h + h2 = 0 Solving for variable 'h'. Begin completing the square. Move the constant term to the right: Add '90' to each side of the equation. -90 + 15h + 90 + h2 = 0 + 90 Reorder the terms: -90 + 90 + 15h + h2 = 0 + 90 Combine like terms: -90 + 90 = 0 0 + 15h + h2 = 0 + 90 15h + h2 = 0 + 90 Combine like terms: 0 + 90 = 90 15h + h2 = 90 The h term is 15h. Take half its coefficient (7.5). Square it (56.25) and add it to both sides. Add '56.25' to each side of the equation. 15h + 56.25 + h2 = 90 + 56.25 Reorder the terms: 56.25 + 15h + h2 = 90 + 56.25 Combine like terms: 90 + 56.25 = 146.25 56.25 + 15h + h2 = 146.25 Factor a perfect square on the left side: (h + 7.5)(h + 7.5) = 146.25 Calculate the square root of the right side: 12.093386622 Break this problem into two subproblems by setting (h + 7.5) equal to 12.093386622 and -12.093386622.Subproblem 1
h + 7.5 = 12.093386622 Simplifying h + 7.5 = 12.093386622 Reorder the terms: 7.5 + h = 12.093386622 Solving 7.5 + h = 12.093386622 Solving for variable 'h'. Move all terms containing h to the left, all other terms to the right. Add '-7.5' to each side of the equation. 7.5 + -7.5 + h = 12.093386622 + -7.5 Combine like terms: 7.5 + -7.5 = 0.0 0.0 + h = 12.093386622 + -7.5 h = 12.093386622 + -7.5 Combine like terms: 12.093386622 + -7.5 = 4.593386622 h = 4.593386622 Simplifying h = 4.593386622Subproblem 2
h + 7.5 = -12.093386622 Simplifying h + 7.5 = -12.093386622 Reorder the terms: 7.5 + h = -12.093386622 Solving 7.5 + h = -12.093386622 Solving for variable 'h'. Move all terms containing h to the left, all other terms to the right. Add '-7.5' to each side of the equation. 7.5 + -7.5 + h = -12.093386622 + -7.5 Combine like terms: 7.5 + -7.5 = 0.0 0.0 + h = -12.093386622 + -7.5 h = -12.093386622 + -7.5 Combine like terms: -12.093386622 + -7.5 = -19.593386622 h = -19.593386622 Simplifying h = -19.593386622Solution
The solution to the problem is based on the solutions from the subproblems. h = {4.593386622, -19.593386622}
