E-CodeQuadratic formula solver — a TI-84 Plus CE program
QUAD is a TI-BASIC program for the TI-84 Plus CE. Prompts for a, b, c and shows both real roots, or reports there are none.
How it's checked
It is run on the TI-BASIC interpreter by E-Code's automated library checks, which also check a computed answer where one is easy to state. It has no oracle case file, so this page gives no case count.
