__3y² - 3__

y² - 1 ------> On problems like these, aren't you suppose to cross out like factors?

Or do you just do that on problems like these:

__x² + 13x + 40__

x² - 2x - 35 ----> do you find like factors (ex. what multiplies to give you 35, and add/subtracts to give you 2? uggh i dont know!

if that is then in this problem i think im heading the right way:

6x² + 5x - 6 = (x+6)(x-1)

3x² - 5x +2 uhmm....still working on it...tehehe.

can somebody please help me understand what are restrictions, how do you find them, and how do you simplify a rational expression?

Please and thank you!! = )
