Question

Solve h(t) = -16t^2 + 16t + 480 where t is time and h is height and finding out how long it would take a ball to hit the ground.

Answer 1

Answer: Factor the problem

Explanation:

Take out the common factor (-16), it will leave you with (t^2 - t - 30)

Factor (t - 6) (t + 5)

t - 6 = 0 or t + 5 = 0

t = 6 seconds
