h(t)=0
so
4.9t^2-25t-12=0
use the quadratic equation, solve for t.
The height of a rocket is launched from a platform 12 meters above the ground is modeled by the function h(t)=-4.9t^2+25t+12 where h(t) represents the height of the rocket in meters and t represents the number of seconds after launching. How many seconds after launching will the rocket return to the ground?
