I have inserted a generic quadratic into the TI-84.

In this instance I entered $x^{2} - 2 x - 6$ $x^2-2x-6$ by using the keys in the following order.

First I pressed the x, t, theta, n key for x.

Next I pressed the $x^{2}$ $x^2$ key.

Next I entered a subtraction followed by 2 then the x, t, theta, n key again.

Finally, I entered a subtraction key followed by a 6.

Lastly, I pressed the grey "graph" button on the top right.
