Set the factor '(2h + -1s)' equal to zero and attempt to solve:

Simplifying
2h + -1s = 0

Solving
2h + -1s = 0

Move all terms containing h to the left, all other terms to the right.

Add 's' to each side of the equation.
2h + -1s + s = 0 + s

Combine like terms: -1s + s = 0
2h + 0 = 0 + s
2h = 0 + s
Remove the zero:
2h = s

Divide each side by '2'.
h = 0.5s

Simplifying
h = 0.5s
Solution
h = {-0.1111111111s, 0.5s}
