So i'm assuming your eqtn is    h = -16t^2 + 27t + 10
and we're looking for t = ?    when  h = 0

=>  16t^2 - 27t - 10 = 0
        (16t + 5)(t - 2) = 0

t = 2  and t = -5/16

Allisa [31]
The Least Common Multiple of 5, 6, 7, and 9 goes into 5, 6, 7, and 9. The Least Common Multiple of 5, 6, 7, and 9 is 630. If you multiply that by 2, 3, 4, and so on, you get a never-ending set of numbers that go into 5, 6, 7, and 9.
