-----  and  -----

Have you ever, in all your experience in adding fractions, ever added denominators for any reason? I hope the answer is "no." Don't do it here, either.

Common denominators are found by multiplication of factors. Least common denominators are found by eliminating common factors. Since you've only two factors, and they are not the same, multiply and you are done.
