Here's a trick to these that's easier than x-box- quadratic formula. Look it up on google, it's not bad at all, plug in your numbers, and you have saved yourself a lot of trouble. If you are required to show work, you can go back and fill in the answers in reverse, and just don't write down all the work you did for the quadratic formula on your paper. :)

could u please help me x-box? I know the quadratic formula I don't understand it that well thanks @Jameskerr1.

Numbers 21, 25, and 26 can be factored. I'll draw something out (sorry, it will take me a while), but it might be easier if you look at them as 2(15x^2-23x+6), 6(-3x^2+2x+1), and 4(3x^2-5x-12). If you don't factor before doing them, they won't turn out right in the end.

Drawing X-Box now, I just wanted to give you that while I was working on it.

how do  x-box them though??

anonymous · Answer

#21 at least cannot be X-Boxed since it has no whole number x intercepts. I would assume the same is for the rest of them, I will check.

anonymous · Answer

Just checked all of them, here's what I've got:

Your results for your X-Box are your "X-Intercepts", or what X is equal to when y is equal to 0. Here is the number of whole number X intercepts for each problem:

21. 0
22. 0
25. 1
26. 1

To be compatible with X-Box, an equation must have exactly 2 whole number x-intercepts and since none of these equations do, they are impossible. Sorry to seem to rain on your parade, but that should have just made your life a whole lot easier.

Good luck!
