Consider the given equation above

The numerator has similar variables and the denominator is a quadratic equation of the difference of two squares. Let's group the numerator with similar variables as follows

Take out their common factor at each group, we have

Factor the denominator as the difference of two squares

The greatest common factor (GCF) of the numerator and denominator is (a + 2). Cross out their GCF and simplify into lowest term. Therefore, the final answer is
