 Question 260945: 2x+1 over (x^2-2x) + 3-x over (5x^2-20) Adding and Subtracting rational expressions. Denominators are in ()Answer by drk(1908)   (Show Source): You can put this solution on YOUR website!here is the original problem: step 1 - factor the denominators to get notice we have a difference of squares still, so we continue factoring as step 2 - the common denominator is 5x(x+2)(x-2). we change the numerators and get a common denominator as step 3 - expand the numerators to get step 4 - combine like terms to get
