Matt hit a foul ball straight up over home plate. The height of the ball over the level of the bat, h(T) is given by the function: h(t)=-16t^2+48t where t is the time in seconds after the ball left the bat. 1. When will the ball reach its maximum height?
2. What is the maximum height of the ball?
3. After how many seconds will the ball hit the catcher's mitt (height = 0)?

a4 - 3a2 - 1

step-by-step explanation:

step   1   :

equation at the end of step   1   :

  ((a4) -   3a2) -   1

step   2   :

trying to factor by splitting the middle term

2.1     factoring   a4-3a2-1  

the first term is,   a4   its coefficient is   1 .

the middle term is,   -3a2   its coefficient is   -3 .

the last term, "the constant", is   -1
