Quadratic functions are functions that has a leading degree of 2. Given the function that represents the height of the rocket as;
y = -16x² + 247x + 141
The point where the rocket will hit the ground is when the height is at 0 feet that is y = 0.
Substitute
-16x² + 247x + 141 = 0
16x² - 247x - 141 = 0
Factorize
On factorizing, the time that the rocket will hit the ground is after 15.99 seconds
