http://www.mathblaster.com/coolmath/articles/adding-rational-expressions NettetYou need to factor your numerator and the denominator to fully reduce the fraction. You also have an error in your numerator 7 (x^2-12x+11) = 7x^2-84x+77 6 (x-1) = 6x-6 7x^2-84x+77+6x-6 = 7x^2-84x+6x+77-6 = 7x^2-78x+71 You have 76 rather than 71 as your last terms. Hope this helps. 3 comments ( 5 votes) Upvote Downvote Flag more Trey Taylor
