Hi! Does anyone know a simple way to program the quadratic formula into a TI-83 (Texas Instruments?) I googled it, but most of the results required downloading (I don't have a connecting cable), or a bunch of keys that I couldn't find on my computer. Let me know if anyone has discovered a good way to do this. Thanks!!!

the formula v=the square root64 can be used to find the velocity v in feet per second of an object that has fallen h feet. Find the velocity of an object that has fallen 23 feet. Round your answer to the nearest hundredth
