Answer 1

What is the common denominator for the two fractions?

Answer 2

x-3

Answer 3

The common denominator is the least common multiple, not the greatest common factor.

Answer 4

In this particular problem it is (x-3)(x+2)

Answer 5

Multiply the second fraction by (x+2)/(x+2). Then the denominators will be the same and you can add the two fractions by adding the numerators and keeping the denominator the same.
