its like elementary long division where you have to carry stuff and the remainders

Answer 27

oh I get it ohkay..

Answer 28

ok. now lets do 9. how did you do that? did you remember to find the common denomniator first?

Answer 29

uhhh no

Answer 30

Is it the 3rd answer?

Answer 31

no. its A.

the first thing is to find their common denominator which is (x-3)(x-2). do you know how to find it?

Answer 32

no.. can you explain to me?

Answer 33

well... theres actually nothing much to explain. because in order to add or subtract two fractions, they must first have the same denominator.
since one of the denominator is x-3 and the other is x-2, the closest thing they have in common would just be (x-3)(x-2)

Answer 34

or with something more simple, lets say you have 1/3 and 4/15. their common denominator would be 15. because 3x5=15 and 15x1=15. 3 and 15 can easily be multiplied by a number to get 15

Answer 35

oh ohkay

Answer 36

so this is what i did
