Variable use between CAS and Home.

[Skyblues]

I wrote the following equation into the CAS:

solve(X^3-5*X^2-2*X+24) and got the result I was expecting ... [-2, 3, 4]

I then wanted to enter the same equation into the Function App to plot it.
I copied the expression within the CAS and pasted in into the Smyb of the Function App. I then deleted solve() so I was left with only X^3-5*X^2-2*X+24. I then pressed Enter.

I got an error which I realized was because in the CAS the 'x' variable was lower case (which was copied over to the Function App). So, I had to change the copied lower case 'x' to upper case 'X' to be able use it in the Function App and plot it.

Is there a better way to do this?
