# Quadratic Formula, math 111, H. Whitehead

**You use the quadratic formula when finding the x-intercepts, or also known as solutions, zeros, answers, and roots.**

### You can find quadratic equations in horse jumping events.

### Word Problem: You have a horse jumping from a height of 6ft above the ground, at a certain angle, the height of the horse above the ground,H, in feet, at time,T, in seconds, is found by the function......

### T= -4.9t2+33.5t+6

### Find the time it takes for the horse to land on the ground.

*a=-4.9, b=33.5, and c=6*
