But what about polynomials with a degree highest exponent that is higher than two These can be difficult to factor with the types of factoring you learn in a high school algebra class This video lesson explains how you can use an app included with the TI 84 Silver Edition to solve a polynomial equation The TI 84 Plus CE and TI 84 Plus C Silver Edition can display either Mathprint or Classic modes to solve equations Mathprint is the default mode to verify or change modes press MODE highlight MATHPRINT or CLASSIC and press ENTER To solve 2x 6 10 in Mathprint mode follow the steps below
1 Press MATH ALPHA B 2 Once you will the two boxes E1 and E2 press x x2 next to E1 3 Arrow down to E2 and press 5 x 6 then press GRAPH to select OK 4 Notice that the equation is now written correctly 5 Input the first guess next to x 6 Press ALPHA ENTER to select SOLVE and the first answer will appear The PolySmlt2 App on your TI 84 Plus CE graphing calculator is the ideal tool for finding roots of polynomials Let s take a look at how to set up your calculator to use this app Check out
