Like I said in my [other explanation](http://socratic.org/questions/how-do-i-graph-f-x-2x-5-x-1-on-a-ti-84

Also keep in mind that you do not need to type out the whole equation into your calculator. You just need to type the numerator of your function, since the denominator has no effect on what the zeroes will be (see my previous explanation to know why).

Hope that helped :)
