Calculators have the technology to handle complex mathematical equations. For example, you can perform factorization on a scientific calculator, such as the TI-84 Plus. Factorization is when you decompose a number, matrix or polynomial and turn it into a product. When you multiply your results, the product should then be the original number.
Press the "Math" button on your TI-84 Plus. Press the "0" key to enter Solver Mode. For the purposes of this tutorial, use the equation X^2-1.
Type in your equation equal to zero. For example, 0=X^2-1. Press "Enter" to determine the results. In this case, the results are 1 and -1.
Subtract the results from X. In this case, the result -- and the answer -- is (X+1)(X-1).
