First, you need to factor the function. You can do this by finding a pair of numbers whose product is equal to the c term (-6) and whose sum is equal to the b term (-5). These numbers are -6 and 1 (-6*1=-6, -6+1=5). The factored expression takes the form:
(x+1)(x-6)=0
The zeroes can be found by flipping the signs in the parentheses. The zeroes are equal to each number.
The zeroes are -1 and 6.
Hope this helps!!

Answer:
5.25 seconds
Step-by-step explanation:
When the ball hits the ground the height is zero
Equate f(t) to zero and solve for t , that is
- 16t² + 84t = 0 ← factor out - 4t from each term
- 4t(4t - 21) = 0
Equate each factor to zero and solve for t
- 4t = 0 ⇒ t = 0
4t - 21 = 0 ⇒ 4t = 21 ⇒ t = 
= 5.25
t = 0 is the time when the ball is kicked
t = 5.25 is the time taken for the ball to hit the ground
