Question By completiing the square determine the maximum height of the ball and how long it takes to reach the maximum height

h=-5t^2+30t+1.5

Work:

=t^2-6t+1.5/5

(t^2-6t+9)1.5/-5 + 9

(t-3)^2+43.5/5

That would mean the time of the ball to get to the max height is 3 seconds but when I graph it I get 6 seconds?
