Alicia watched a drone take off from a bridge. The height of the drone (in meters above the ground) minutes after takeoff is modeled by h(t)=−3t2+12t+96h(t)=-3t^2+12t+96h( t)=−3t2+12t+96h, left parenthesis, t, right parenthesis, equals, minus, 3, t, squared, plus, 12, t, plus, 96 Alicia wants to know when the drone will land on the ground. 1) Rewrite the function in a different form (factored or vertex) where the answer appears as a number in the equation. h(t)=h(t)=h(t)=h, left parenthesis, t, right parenthesis, equals 2) How many minutes after takeoff does the drone land on the ground?
