Rational expressions....ok clueless. im not sure what steps to follow thru with.
Directions: Simplify each rational expression. State any restirctions on variable.
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!! = )
