Many people dislike having fractions in their problems. So, if you are one of them, multiply each side of the equal sign by the Least Common Denominator (18 in this case).

Problems becomes n^2 - 9h + 18 = 0

Factor: (h - 6)(h - 3) = 0

Two h's, so two possible answers. Either h - 6 = 0 or h - 3 = 0.

Answers: {3, 6}
