Thank you for all of your help. I'll ask my teacher tommorow. Also, something does cancel out. If you factor x² + x - 30 you get (x + 6)(x - 5), and if you factor x² - 36 you get (x + 6)(x - 6). The (x + 6)' s cancel each other other out.

Yes, I'm positive about the 2x² + 9x -10. I guess my teacher didn't write the problem correctly. I know how to factor the x² + x - 30 and the x² - 36, but not the other two.

I'm terribly sorry, it's x² + x - 30, not x² + x -10, but I can factor that. Also, can you explain, please, I have to go to bed soon.

It's impossible to factor "2x² + 9x -10" isn't it?

Well, I need help solving the next problem: All you have to do is simplify it. Also, would you be so kind and show your work? Thank you.
