Best ResponseYou've already chosen the best response.0Before we start answering your question, is this the expression you have? \[(x^{3} + 1)/(x^{2}  1) * (3x  3) / (x{3}  x^{2}+x) \]

Best ResponseYou've already chosen the best response.0Since x^3 + 1 is a sum of cubes it factors into (x+1)(x^2  x + 1)

Best ResponseYou've already chosen the best response.0and then below that I would put (x+1)(x1) right

Best ResponseYou've already chosen the best response.0Correct. For the second fraction, the numerator can be factored by taking out the common factor of 3 and the denominator can be factored by taking out the common factor of x.

Best ResponseYou've already chosen the best response.0Oh so then it would be 3(x1) / x(x^2x+1) ? or do I not put the 1

Best ResponseYou've already chosen the best response.0You should still have a 3 in the numerator and an x in the denominator.

Best ResponseYou've already chosen the best response.0Oh yeah I totally ignored that. So my answer would be 3/X
