Question 420178
3/(x - 2) + 3/(x + 2)
3(x + 2)/(x + 2)(x - 2) + 3(x - 2)/(x + 2)(x - 2) {got the common denominator, (x + 2)(x - 2)}


3(x + 2) + 3(x - 2)
------------------- {combined numerators over common denominator}
(x + 2)(x - 2)


3x + 6 + 3x - 6
---------------- {used distributive property}
(x + 2)(x - 2)


6x 
-------------- {combined like terms in numerator}
(x + 2)(x - 2)
