During softball practice, a softball pitcher throws a ball whose height can be modeled by the equation h = 16t^2 (<squared) + 24t + 1, where h=height in feet and t = time in seconds. How long does it take for the ball to reach a height of 6 feet?

just plug in the numbers:
6 = 16t^2 + 24t + 1
16t^2  24t + 5 = 0
(4t1)(4t5) = 0
t = 1/4 (ball rising)
t = 5/4 (ball falling)
