The Quadratic formula is used to solve for the X-intercepts, also known as solutions, zeros, answers, and roots.
Quadratic formulas are everywhere
Everything from the arc of a rainbow off on the horizon, to a cannon firing a round through the air and even a dolphin leaping over the surface of water.
If the cannon shoots a projectile when it's 15 feet off of the ground and the parabolic flight path is modeled by h = 1t^2-8t+15, what is the amount of time in seconds until the cannonball hits the ground?
Time for the Quadratic Formula to come into effect.
More paper is required, I do believe.
