Subproblem 1

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

Subproblem 2

Set the factor '(1 + -1h)' equal to zero and attempt to solve: Simplifying 1 + -1h = 0 Solving 1 + -1h = 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 + -1h = 0 + -1 Combine like terms: 1 + -1 = 0 0 + -1h = 0 + -1 -1h = 0 + -1 Combine like terms: 0 + -1 = -1 -1h = -1 Divide each side by '-1'. h = 1 Simplifying h = 1

Solution

h = {2, 1}
