This document provides instructions for solving a quadratic equation both algebraically and graphically using a TI-Nspire calculator. It outlines the keystrokes to use the SOLVE() function to solve the equation algebraically and describes how to graph the equation and find the x-intercepts/roots by pressing left/right arrow buttons continuously. The document suggests toggling between the algebraic and graphical windows using up/down arrow buttons to compare the solutions.
