You add rational functions just as you would add rational numbers (fractions) by first finding a common denominator. For example to add 1/3 and 1/15 I can see that 15 = 3 × 5 so 15 is a common denominator and hence Now let's try 1/(x  1)  1/(x^{2} + x  2). Again I need a common denominator and since x^{2} + x  2 = (x  1)(x + 2) I can use x^{2}  x  2 as a common denominator. Thus Now you try 1/(x+3) + 1/(x^2+5x+6) . If you need further assistance write back.
