Best ResponseYou've already chosen the best response.1Hello, 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?

Best ResponseYou've already chosen the best response.1Correct! Now, you see the x + 1's will cancel, leaving you with \[\frac{ 15 }{ x  1 }\]

Best ResponseYou've already chosen the best response.0So: (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.

Best ResponseYou've already chosen the best response.1No, 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.
