Subproblem 1

Set the factor 'h' equal to zero and attempt to solve: Simplifying h = 0 Solving h = 0 Move all terms containing h to the left, all other terms to the right. Simplifying h = 0

Subproblem 2

Set the factor '(5k + 4h)' equal to zero and attempt to solve: Simplifying 5k + 4h = 0 Reorder the terms: 4h + 5k = 0 Solving 4h + 5k = 0 Move all terms containing h to the left, all other terms to the right. Add '-5k' to each side of the equation. 4h + 5k + -5k = 0 + -5k Combine like terms: 5k + -5k = 0 4h + 0 = 0 + -5k 4h = 0 + -5k Remove the zero: 4h = -5k Divide each side by '4'. h = -1.25k Simplifying h = -1.25k

Subproblem 3

Set the factor '(-5k + 4h)' equal to zero and attempt to solve: Simplifying -5k + 4h = 0 Reorder the terms: 4h + -5k = 0 Solving 4h + -5k = 0 Move all terms containing h to the left, all other terms to the right. Add '5k' to each side of the equation. 4h + -5k + 5k = 0 + 5k Combine like terms: -5k + 5k = 0 4h + 0 = 0 + 5k 4h = 0 + 5k Remove the zero: 4h = 5k Divide each side by '4'. h = 1.25k Simplifying h = 1.25k

Solution

h = {0, -1.25k, 1.25k}
