Hello, my name is Stephen and I will be your tutor. The first step is to factor the bottom terms and top terms, do you see any possible factors, Mikeyy?

Is that correct?

Correct! Now, you see the x + 1's will cancel, leaving you with \[\frac{ 15 }{ x  1 }\]

So: (x + 1) would cancel out (x + 1) and not (x  1) I thought negative would cancel out a positive and other way around. That's where I got confused.

No, that's not the case. Only like terms can cancel each other, for example, if I had \[\frac{ x  y }{ x  a }\] The terms cannot cancel, nor can the x's, because x  y and x  a, are terms themselves. You need to understand that. Now, if I had: x  y over x  y, then I could cancel. Only terms that are exactly the same can be canceled.
