The first thing we want to do here is find our least common denominator for these.
00:04
The way we do that is by pulling out everything we have, making sure we don't have any repetition.
00:09
So let's start with find least common denominator.
00:12
Between both of the denominators, they both have a c minus 3.
00:15
Since they each have it, and there's only one of them, i'm going to list that once.
00:20
Then we look at what each one has as an individual.
00:23
So this one on the top, i see that it has a c plus 9.
00:26
That one does not exist in the second one, so that has to be part of the least common denominator.
00:30
For the bottom one, i see that one has a c plus 4, the top one does not have.
00:34
So i'm going to include that in there as well.
00:36
Now to rewrite things to have that least common denominator, we're going to have to multiply by what's missing.
00:41
So for the fraction of the top, we're missing the c plus 4...
