Best ResponseYou've already chosen the best response.0To start with you factor (x^21) and you get (x+1) (x1) so it's now x/(x+1)(x1)  2/(x+1) in order to subtract these two terms they need a common denominator. so you multiply the second expression by (x1) to make it look like the first, 2 (x 1) = 2x 2 Now you can subtract both terms, x  2x +2 = x +2 write the new term above the denominator, (x+2)/(x^21)
