1. The first one has the common denominator of x, so just subtract the numerators : )

2. needs a common denominator. To make the common denominator of c^2 you must multiply the numerator and denominator of the first fraction by c thus
= 6c/c^2 + 4/c^2
= (6c + 4)/c^2
you could factor out of the top, but it wouldn't change the rational expression : )

3. Factor both denominators and find your common denominator, then continue : )

4. YIPPEEEE! Long division (or synthetic division) your choice : )
