Factoring, you have
h(t) = -16(t^2 -2 -8) = -16(t -4)(t +2)
The ball hits the ground when h(t) = 0, so
0 = -16(t -4)(t +2)
t = 4 or -2
The positive solution is the one of interest.
It will take 4 seconds for the ball to hit the ground.

Step-by-step explanation:
3x - 7 = 2x - 5<em> add 7 to both sides</em>
3x = 2x + 2 <em>subtract 2x from borh sides</em>
<h3>x = 2</h3>
Check:
L = 3(2) - 7 = 6 - 7 = -1
R = 2(2) - 5 = 4 - 5 = -1
L = R CORRECT! :)
