Right now I am teaching myself Algebra 1 and Algebra 2, but I find it more so of a time sink than actually learning anything when factoring quadratic polynomials with a coefficient attached to $\displaystyle x^2$

e.g. $\displaystyle 2x^2-5x-12$, and give you the correct output of $\displaystyle (2x+3)(x-4)$

So with that being said does anyone know of a ti83 program that will automatically factor these types of quadratic polynomials?

Many Thanks
