Question

2. Jennifer kicked a soccer ball from the ground and it followed the projectile

h(t) = x2 + x - 6, where t is the time in seconds and h is the height of the ball.
How long does it take for the ball to hit the ground?

Answer 1

2

Explanation:

To solve this equation I used the quadratic formula.

1. Place the units into the following formula. -b+-sqrtb^2-4ac

2a

2. After placing the units into the formula it should be -1+-sqrt1+24

2

3. This should leave you with two possible answers -3 and 2 after solving it. The answer can not be negative of course cause there is no such thing as a negative time. So the answer has to be 2.
