Do the left numerator by factoring the denominator: = Do the left denominator by getting an LCD of (x-2): = = = So we have The first term is a fraction divided by a fraction, so So we invert the second fraction and change the division to multiplication. We cancel the (x-2)'s We cancel the (x-1)'s Get an LCD of (x+2)(x-2) So the answer has -4 in the numerator, not +4. Edwin
