Subproblem 1

Set the factor '(285 + -12h + -4h2)' equal to zero and attempt to solve: Simplifying 285 + -12h + -4h2 = 0 Solving 285 + -12h + -4h2 = 0 Begin completing the square. Divide all terms by -4 the coefficient of the squared term: Divide each side by '-4'. -71.25 + 3h + h2 = 0 Move the constant term to the right: Add '71.25' to each side of the equation. -71.25 + 3h + 71.25 + h2 = 0 + 71.25 Reorder the terms: -71.25 + 71.25 + 3h + h2 = 0 + 71.25 Combine like terms: -71.25 + 71.25 = 0.00 0.00 + 3h + h2 = 0 + 71.25 3h + h2 = 0 + 71.25 Combine like terms: 0 + 71.25 = 71.25 3h + h2 = 71.25 The h term is 3h. Take half its coefficient (1.5). Square it (2.25) and add it to both sides. Add '2.25' to each side of the equation. 3h + 2.25 + h2 = 71.25 + 2.25 Reorder the terms: 2.25 + 3h + h2 = 71.25 + 2.25 Combine like terms: 71.25 + 2.25 = 73.5 2.25 + 3h + h2 = 73.5 Factor a perfect square on the left side: (h + 1.5)(h + 1.5) = 73.5 Calculate the square root of the right side: 8.5732141 Break this problem into two subproblems by setting (h + 1.5) equal to 8.5732141 and -8.5732141.

Subproblem 1

h + 1.5 = 8.5732141 Simplifying h + 1.5 = 8.5732141 Reorder the terms: 1.5 + h = 8.5732141 Solving 1.5 + h = 8.5732141 Solving for variable 'h'. Move all terms containing h to the left, all other terms to the right. Add '-1.5' to each side of the equation. 1.5 + -1.5 + h = 8.5732141 + -1.5 Combine like terms: 1.5 + -1.5 = 0.0 0.0 + h = 8.5732141 + -1.5 h = 8.5732141 + -1.5 Combine like terms: 8.5732141 + -1.5 = 7.0732141 h = 7.0732141 Simplifying h = 7.0732141

Subproblem 2

h + 1.5 = -8.5732141 Simplifying h + 1.5 = -8.5732141 Reorder the terms: 1.5 + h = -8.5732141 Solving 1.5 + h = -8.5732141 Solving for variable 'h'. Move all terms containing h to the left, all other terms to the right. Add '-1.5' to each side of the equation. 1.5 + -1.5 + h = -8.5732141 + -1.5 Combine like terms: 1.5 + -1.5 = 0.0 0.0 + h = -8.5732141 + -1.5 h = -8.5732141 + -1.5 Combine like terms: -8.5732141 + -1.5 = -10.0732141 h = -10.0732141 Simplifying h = -10.0732141

Solution
