Question

What are the zeros of the function? h(t)=(t -4)(t+8)

Answer 1

4 and -8

Explanation:

Anything multiplied by 0 is 0. So we just need to find values of t which will give you a 0 by setting them equal to 0

`t - 4 = 0\\\\t = 4\\\\t + 8 = 0\\\\t = -8`

Answer 2

Find when h(t) = 0
0 = (t-4) (t+8)
t = 4, t = -8
