Yes, this is an algebraic expression, and is the simplest possible. Cannot be simplified further, and cannot be factored.

If we know the value of x, we can evaluate it to a number, otherwise, it stays as it is.

First find the time that the ball is level with the top of the building on its descent. You can do this by solving 280 = -16^2 + 48t + 280 for t. This gives t = 3 seconds .
Then when the ball reaches the ground the time t is obtained by solving 0 = -16t^2 + 48t + 280 This gives t = 5.94 seconds.
Answer in interval notation is (3, 5.94].
