Answer 1

Hit [math] [^] and [enter] That gets you to the equation solver.
Hit [^] to type in the equation.
When putting in a minus sign make sure you use [-] and not [(-)]
Here's an example:
y = x^2 - 10x + 24
That factors into (x - 4)(x - 6), so we already know the answers are 4 and 6.
The trick is you have to make a guess. If you don't make a guess, it makes one for you.
at x = , type in 3, then hit [alpha] [solve]. It gives you the answer closest to 3, namely 4.
Now you want the other answer, but if you put in guesses that are closer to 4 you'll keep getting 4, you won't get the 6.
Put in a guess that's closer to 6 than it is to 4, then you'll get the 6.
