Subproblem 1

Set the factor '(5 + 2h)' equal to zero and attempt to solve: Simplifying 5 + 2h = 0 Solving 5 + 2h = 0 Move all terms containing h to the left, all other terms to the right. Add '-5' to each side of the equation. 5 + -5 + 2h = 0 + -5 Combine like terms: 5 + -5 = 0 0 + 2h = 0 + -5 2h = 0 + -5 Combine like terms: 0 + -5 = -5 2h = -5 Divide each side by '2'. h = -2.5 Simplifying h = -2.5

Subproblem 2

Set the factor '(1 + h)' equal to zero and attempt to solve: Simplifying 1 + h = 0 Solving 1 + h = 0 Move all terms containing h to the left, all other terms to the right. Add '-1' to each side of the equation. 1 + -1 + h = 0 + -1 Combine like terms: 1 + -1 = 0 0 + h = 0 + -1 h = 0 + -1 Combine like terms: 0 + -1 = -1 h = -1 Simplifying h = -1

Solution

h = {-2.5, -1}
