2x-9/x-5 - x^{2 }+ 4x-5/x^{2} - 25 =2x-9/x-5 - (x+5)(x-1)/(x-5)(x+5) =2x-9/x-5 - x-1/x-5 =2x-9-x-1/x-5 =x-10/x-5 Aug 22 | Nikky from Claymont, DE | 2 Answers | 0 Votes Mark favorite Subscribe Comment
line 4 should be =2x-9-x+1/x-5 because -(x-1)=-x+1 line 5 then would be x-8/x-5 by the way, try to use parentheses to make your work easier Aug 22 | Arthur D. Comment
