Solving quadratic inequalities on a TI Nspire graphing calculator involves determining the values of the variable that satisfy the inequality. Quadratic inequalities are expressed in the form ax + bx + c > 0, ax + bx + c < 0, ax + bx + c 0, or ax + bx + c 0, where a, b, and c are real numbers and a 0. To solve these inequalities using the TI Nspire, follow these steps:
1. Enter the quadratic inequality into the calculator. For example, to enter the inequality x – 4x + 3 > 0, press the “y=” button and enter “x^2 – 4x + 3 > 0”.
